Cheyrou's position is very difficult. He's at best 4th, perhaps 3rd pick for roles in CM.
Behind one or two strikers;
Smicer, Kewell, Le Tallec ahead of him.
CM
Gerrard, Hamann, Murphy,....
LM
Kewell, Murphy, Smicer, Riise
I think he will get a couple of more games, but it's difficult to see how he can make the team say 5 games in a row. It's sad for Bruno, he's never had a proper chance. If he was to leave right now, nobody would notice. It's hard to argue why he should have a place in the squad. The same can be said about a few other players too.
