Tbf, they would be my concerns too. It's great Martinez has said what he's said and it looks (at least at this stage) like Everton are heading for a moral victory, but you have to ask at what cost?
He's an average defender, at best, without the ball at his feet, as he underlined again last night. He has plenty of mistakes in him - mistakes that were brushed under the carpet so far by supporters but who wont be in such forgiving mood from now on. The window remains open and there's still deals that could be cut. If it were me I'd be arranging incomings on the basis of a last day/48 hour sale. We'd just have to deal with the fallout of selling after saying he's not for sale. We have to be pragmatic here. This player's value wont be going up to this level again, imo.
