I can't see Zenden playing Garcia's role, and to be fair I think Gonzalez will take Kewell's place in the team, as good as Harry has been he is pretty slow and as for whipping the ball in, his crosses aren't that good for a winger.
Riise is meant to have a bit of a problem with Rafa and vice versa, so I think he will go and so will Kewell, his wages are astronomical and he is only just showing form now. If Gonzalez is as good as people says, then Kewell is a bit expensive to have sitting on the bench.
I think Zenden will be more happy to be a squad player
