I've a feeling somethings gone on behind the scenes, like a promise made to him didn't come through (contract/wage rise) or felt his injuries were badly handled.
I think he's just been told he wouldn't be a starter mate and he threw his toys out of the pram a bit.
That being said he has also been injured a lot.
But he's too safe.
I was one of his biggest defenders on here as I always thought if he just added 'more' to his game he'd be the perfect all-rounder.
Ultimately he has shown in the games he's played this season he can't do that, and I'd rather move him on if he doesn't want to be here.
