I disagree with everything you have said there.He isn't that good on the ball, instead he delays delivering the ball and gets caught in possession frequently.Aside from the pass for Osman, which I admit was impressive, he hasn't proved a thing.The argument that he is injured and needs match fitness is false hope for me.The argument is disregarded when applied to Arteta, yet everyone clings to it where Fernandes is concerned.
We do not know he is a quality midfielder and hence shouldn't sign him, based on cureent evidence.
