Former Aberdeen boss Derek McInnes has revealed for the first time the moral dilemma he faced over Scott McKenna's proposed switch to Aston Villa in 2018.
The Dons turned down a £5m-plus-offer for their prized asset as they held out for £7m from the Villans, with Celtic also keen at the time.
The Scotland international eventually left the Granite City for Nottingham Forest in 2020, for a fee of £3m with add-ons which could yet see Aberdeen secure £6m for their record sale.
