What we need is a manager who can judge a player and has a clear plan on how he'd use them.
We've gone from Moyes who, through circumstances and his personality, clearly evaluated players before he signed them. We had a set system of play and he signed players we needed.
Went to Roberto who started off like this then suddenly started signing players who didn't really fit in with the way he played, and by the end seemed to lose the plot altogether.
Koeman (or Walsh who knows) have taken this to the extreme, he want to play a 4-3-3 with a solid base, 3 mobile midfielders, a strong striker and 2 pacey wide attackers and somehow ends up with a team of very slow players who can play #10 and no striker.
