The work is expected to take around two months to complete. An official club statement confirmed 'three larger stones dedicated to former managers Don Revie, Howard Wilkinson and Marcelo Bielsa' will also be installed, 'similar to those located in Bremner Square', while additional space for supporters to purchase new stones has also been factored into the project. “The club have taken on board recent feedback from supporters on the stones at Centenary Square, and we are really happy that we can now announce that all of the stones will be replaced," chief executive Angus Kinnear confirmed,
