I think I could make a reasonable case, if I argued that his contribution this season is still among the best of our squad. Although I have to say that quantitywise i'd make a less impressive case.
You can make a case if you say that this season went to hell immediately after his injury.
Not that one can claim how his injury was the reason for our fiasco, but you'll be very close to the truth if you say that it was one of the reasons for that.
He was easily our #1 player until November. He got injured, Ferrara changed the formation, all went to hell.
When he came back the season was already lost, the atmosphere wasn't healthy at all and he did suck. But he was very good before that.
Personally I am not scared of his form. It's more about his injuries that scare me and our dependence on Camo on the wings. If he's still here, getting the same wages, I don't think we will buy a great winger. And I could accept that if Camo wasn't injury prone. But he isn't and I don't want Camo's sub to play 70% of the season, knowing that Camo's sub won't be a good player (unless we get super lucky with some youngster).
