You can't deny that so far Vic has been crap, he doesn't deserve to play. I don't mind if he doesn't run around like AJ but not jumping for headers is a joke. I've only ever seen him play well once, and for that game I thought I was wrong about him but since then he's gone back to looking like he doesn't want to be on the pitch. Once Vaughan is back and fit he should be loaned out to teach him that he can't just huff and puff and watch the game go on around him.
You said Carsley was one of our best performers last season. Like you said last season, we're now onto a new season and he's been average at best. Maybe dropping him for Jags will give him the kick up the arse he needs, but to me his reading of the play (which is something a DM needs to do well) has slowed right down, and is pretty non-existent now. Jagielka deserves to play ahead of him this weekend, and once (or if) Jagielka loses form I'll have no problem with Carsley coming back in.
