Brenden Aaronson: why Leeds pushed hard for signing and what USMNT midfielder will bring - The Athletic 24/5/22

Athletic in February 2022. It has been updated to reflect Brenden Aaronson’s
appearances since then, including his upcoming move to Leeds United)
Within an hour of Leeds United averting demotion from the
Premier League on Sunday, it was business as usual. Relegation threatened no
end of summer turmoil at Elland Road, but it was clear in no time that survival
on the last weekend of the season had kept a plethora of plans intact.
As the dust settled at Brentford, word reached The Athletic
that a deal had been agreed with RB Salzburg for Brenden Aaronson, the initial
fee set at around £25 million. Leeds had tried and failed to sign the
midfielder in January and it was always their intention to try again this
summer, but it went without saying that the move would collapse if Leeds went
down.
Salzburg rejected two offers at the turn of the year but it
was telling that, within no time of the season finishing on Sunday, one
transfer agreement at Leeds was already a long way down the road. Aaronson is
yet to undergo a medical in England, but Leeds are close to announcing that a
deal with Salzburg is in place and finalising personal terms with the USMNT
international should not hit any snags.
All being well, they will get their man and all the quality
they hope he will bring.
The reaction to Leeds’ second bid for Aaronson in January
was confirmation that a transfer would have to wait for another window.
Salzburg paid it no attention — a means of telling Leeds their prior resistance
to selling Aaronson was not a bluff or an attempt to drive up the fee. Game
over, if only temporarily.
The offers from Elland Road began at £15 million and rose to £20 million a few days later, but the message from the perennial Austrian champions at the end of December — that their squad would remain intact throughout January, whatever the fees dangled in front of them — held firm. Leeds deduced from Salzburg’s unresponsive state that there was no point in returning with a third bid. The club decided in advance of the January deadline that they would try again for the US international midfielder at the end of the season.
Salzburg had a ninth straight domestic title and a first
Champions League knockout phase campaign to concentrate on, but when their own
season finished they were always likely to be more open to fielding approaches
for Aaronson, being sympathetic to his own ambition. Leeds’ effort in keeping
their interest alive underlined the fact that they had been following the
21-year-old for longer than someone who represents a short-term solution.
Aaronson was unable to influence their Premier League fate, and the midfield at
Elland Road was left as short on bodies as it was when the January window
opened, but they saw plenty of future value in him.
There was confidence in Aaronson’s potential and ability,
and confidence in his character too. Leeds sought references about him, some
from coaches who have worked with him in the past, and Aaronson — despite
refusing to make any attempt to force his way out of Salzburg in January — was
highly receptive to the idea of moving to England. Leeds’ head coach, Jesse
Marsch, is the coach who was in charge of Salzburg when Aaronson moved to
Austria from the States in January 2021.
But why the fixation on Aaronson, and why the insistence on
waiting for a second bite at him when other attacking midfielders were
available in the January window — not to mention the window that lies ahead?
With every target Leeds analyse, attention is paid to how closely a footballer matches up with the club’s style of play. The club had very pronounced tactics under Marcelo Bielsa and, though the Argentinian was sacked a few weeks after the original bids for Aaronson, Leeds believed that he would match up well to Bielsa’s tactics. They believed too that Aaronson’s attributes would allow him to work and adapt for a different manager and Marsch — who he had already played for — was at the top of the list of candidates to take the job at Elland Road as and when Bielsa left. If Aaronson was good enough to fit in January, it stood to reason that he should fit at a later date too — suitable for whoever followed in Bielsa’s footsteps.
Victor Orta, Leeds’ director of football, had approached
negotiations with other signings in the past, Robin Koch for example, by using
video footage to outline what would be asked of them at Elland Road: what their
role would be, the precise responsibilities that role would entail and how
their performances for their existing club compared or contrasted with Leeds’
style. Footage for Aaronson was prepared and ready to go in January, waiting
only for Salzburg to accept a bid. The presentation amounted to a developmental
plan that Leeds are now poised to implement.
In Aaronson they identified clear shades of Mateusz Klich
and it could be argued that Klich’s position — the bridge between the midfield
four and No 10 — is one of the areas where the club are most in need of
additional numbers and quality. Bielsa asked Kalvin Phillips to keep order in
front of the back line but in more advanced areas there was a long-standing
lack of players who could operate in a more box-to-box fashion and construct
attacks through the middle third and beyond. Leeds failed to address that
shortage last summer, missing out on Chelsea’s Conor Gallagher, and chose to
hold fire in January after Salzburg knocked back their interest in Aaronson.
Klich’s form has been intermittent in the Premier League, but for long stretches of the Bielsa era he was pivotal in making collective performances tick. The Poland international likes to vary his position, dropping deep to help Leeds pass their way through the opposition and using positive forward runs to provide an outlet as soon as he releases the ball. When he shines, his movement makes him difficult to mark and allows Leeds to attack quickly in transition, moving play around the field and taking advantage of gaps in the opposition’s structure. The interplay utilised the pace in Leeds’ squad and helped them to advance through a structured press.
Marsch’s tactics, or those seen to date, are unlike Bielsa’s
— and Klich has been in and out of the club’s lineup during Marsch’s 12 games
in charge. It remains to be seen how prominent Klich is from here on. Aaronson
has many promising traits — in terms of age alone, he turned 21 in October
while Klich will be 32 by the time next season starts. To an extent, recruiting
Aaronson prepares the ground for a passing of the baton.
The New Jersey-born Aaronson’s career has been on a
promising incline since his 2019 breakthrough season with his local MLS club,
Philadelphia Union. Sources at Leeds say he was tracked first by their
emerging-talent team — the scouts who focus on age groups below proven
first-team ranks — and remained on the radar as he established himself as
first-team ready for teams outside America. He had turned 20 when Salzburg finalised
a deal for him in late 2020, a transfer that officially went through in last
year’s January window.
Neither MLS nor Austria’s Bundesliga is on a direct competitive level with the Premier League and Salzburg’s financial might has made them incredibly dominant domestically. This season they finished top of the table by a margin of 18 points, losing only one league game. But moving to Austria took Aaronson into the Europa League and then the Champions League and Salzburg saw no reason to hold him back.
Of the eight games needed to progress to their Champions League last-16 ties against Bayern Munich in February, Aaronson started seven. He also started both legs against Bayern, producing two assists — albeit in an 8-2 aggregate defeat. A change of formation awaits him in Leeds, unless Marsch happens to turn to the 4-4-2 diamond system that Salzburg are virtually wedded to. Marsch, more often than not, has gone 4-2-3-1 in the Premier League.
By joining Salzburg, Aaronson’s physical output was going to be tested from the very start. Either he took a good engine with him from the States or he would have to show a willingness to develop one as soon as he arrived. Salzburg’s football is possession-based, but they are renowned for a strict and bullish press without the ball, chasing recoveries in high areas. It is physically demanding and the requirements have been reflected in Aaronson’s domestic performances.
Skillcorner’s analysis shows that in a typical 90-minute
game, Aaronson will cover an average of 10.7km, ranking him in the top five
midfielders in Austria’s Bundesliga to have played 10 or more games this
season. That is in line with some of the best 90-minute distances registered by
players in the Premier League — potential Elland Road colleague Adam Forshaw,
for instance, was hitting 10.9km after his return from injury — and the numbers
impressed Leeds, who consistently rack up more kilometres than any other team
in England’s top division.
Aaronson is a committed and active presser and 27.2 pressures
per 90 minutes, as calculated by Statsbomb via FBref, is on a par with the very
best of Europe’s attacking midfielders — in the top two per cent across the big
five European leagues.
To give the data below some context, the higher the percentile Aaronson falls into, the more impressive the comparison with his contemporaries. His high-speed running is relentless too. He is not an especially great defender, but his energy, as part of a deliberate press, suggests his running off the ball helps team-mates to position themselves and step in rather than relying on specific interventions from Aaronson himself.
While the difference in quality between the Austrian
Bundesliga and other competitions can be analysed in technical terms,
Aaronson’s physical numbers would transfer easily from league to league.
Straight away, it is easy to see why his name came up when Leeds applied other factors like position, valuation and potential. Most footballers required a period of acclimatisation under Bielsa, but had he signed in January Aaronson appeared to be in the right shape to make an impact straight away. It is reasonable to assume, therefore, that he will be in the right shape to settle in quickly this summer.
To get a feel for his attributes on the ball, it is
necessary to dig deeper into his characteristics.
The picture that develops is, as Leeds concluded, similar to
that painted by many of Klich’s displays. Aaronson is a low-involvement player
in the sense that there are others on the pitch who touch the ball and pass it
far more than him. An average of 30.5 passes per 90 is low for a player in his
position, but while Klich posts a higher average of 43.6 per 90, it is only
marginally above the bottom third. The key for footballers with passing stats
like theirs is to ensure that quality eclipses quantity.
Aaronson’s progressive passing is also limited and as the
smarterscout graphic details below, he prefers neater, shorter passes leading
to a high volume of link-up play — again, like Klich.
Some of the ratings in this graphic are adjusted to take into account the Premier League’s superior level of quality. Klich has never been a prolific carrier of the ball and does not make an especially high number of progressive passes either, but he is very good at receiving them — a strength Aaronson possesses too. Klich’s style is as much about making himself available for forward balls as it is about supplying them; laying the ball off, then offering himself as an outlet in advanced spaces.
With Bielsa, it was likely that his possession-based philosophy would impact on the progressive passes that come from a player in the zone behind a centre-forward or pair of strikers. Marsch’s Leeds do not seek to dominate to the same degree, but he will also have to find ways to bring Aaronson’s on. Salzburg’s style consistently allowed Aaronson to get into advanced areas and he has had a consistent knack of popping up in the opposition box, often with third-man runs. His shot volume is not too high (59 out of 99) but considering the touches he averages over 90 minutes, he is minded to get efforts on goal when he can.
On the attacking front, his data could not be described as remarkable. The chances he creates himself (xG from shot creation) or through progressive play (xG from ball progression) are sometimes of a relatively low value — especially when adjusting for Premier League standard — though he finished this season with four league goals and four assists from 26 appearances. In Salzburg’s Champions League run, he produced 1.5 open-play chances per 90 and turned in a particularly good performance during their first leg against Bayern, a match that ended 1-1. Salzburg were completely outplayed in the return fixture, losing 7-1 on the night.
To say that Leeds are not signing the finished article is to
accept that Aaronson is 21 and has only been in European football for 18
months. Klich, despite mixed form, scores extremely highly for creating
opportunities for Leeds, taking shots himself and threatening assists. Aaronson
is on a promising curve, but by coming to England and Elland Road his game will
have to successfully go through a fresh stage of evolution. Not for the first
time, Leeds are investing in a prospect.
In this window — and after such a close shave with
relegation — the club are under pressure to hit the mark with their
recruitment. An outlay of £25 million on Aaronson is a sizeable commitment, but
his potential has seduced Leeds and their only concern was that after failing
to sign him in January, the boat might sail. At that stage, reports on the
continent talked of rival interest from AC Milan and RB Leipzig, the biggest
club in the Red Bull stable, and Aaronson’s reputation was by no means off the
grid. But Leeds had their claws into this deal and, survival permitting, did
not intend to let it go.
