New Leeds United boss Steve Evans will be an unfamiliar figure to the majority of the club's players.
Yet there is one who has already worked under Evans, with Scott Wootton signed on loan by the Millers at Rotherham United last year.
Evans even attempted to sign Wootton permanently, only to have the deal blocked, with the manager stating it was Cellino's decision.
He told the Yorkshire Evening Post: "Scott Wootton has gone back to Leeds. I thought it was all agreed with Neil (Redfearn).
"Mr Cellino makes the decisions as we know and Neil has never hidden from that. Mr Cellino at this moment in time has said no and we have to respect that.”
Wootton had been seen as surplus to requirements after a difficult start to his Leeds career, but after being kept on in January, began to turn his fortunes around.
He won a place in the team at right-back with Sam Byram pushed further forward, and signed a contract extension.
This season he has been on the outside looking in, with Uwe Rosler bemusingly picking him in central midfield in the League Cup, in an ill fated experiment.
At right-back he has lost his place to the excellent Gaetano Berardi, while Sam Byram is back in contention for the position, and he is fourth choice centre-back behind Sol Bamba, Liam Cooper and Giuseppe Bellusci.
Evans may have other ideas. Wootton made seven appearances for Rotherham over a six week period, and made such an impression that he wanted him permanently.
Just like Evans, the former Manchester United centre-back is not a fan favourite at Elland Road, yet this odd couple could attempt to beat the odds to become an unlikely success.
