In the majority of cases they get worse. We could get the whole of Man Utd team in on loan and in three weeks they would be playing the same old crap football we are seeing now. Time some 'I love Davey' brigade realised 'tactically' he has no idea. Look at the JCR positional play of late and why is Anderson de Silva rubbish the last few matches when he was a premiership player not so long ago. All are effected by Daveys guidance. You may laugh but even Oddjob could improve with the right Manager.
JCR Mi mam played better than him when he first came to the club. Now were turning down million pound offers. Muller and Anderson I maybe agree with you, but both have had severe injuries in the mean time. But JCR -??? yes he should play on the wing, and maybe his improvement isn't specifically down to Davey, Both these you can say. but he is a much better player than when he arrived.
In my view JCR is a better player now than when he first joined us. He certainly hasn't become a poorer player under Davey, but why spoil another anti-Davey thread.
He certainly has made him poorer this term , by playing him in CENTRE MIDFIELD He is a decent winger , but a poor central midfielder. Trouble withy JCR is that he now thinks he is the dogs danglies and he has believed all the hype and ******** spouted about him by the manager.
