I think it's all mind games.
My thoughts are Ched isn't injured, he's returned to the clubs expecting things to be 'as they were'. He's putting pressure on himself, he wants to repay the fans who stood by him and things aren't going as planned, in his head.
Personally I think Ched has contributed when he's come on, he needs time to get back up to speed with life in the championship but a couple of goals will do his confidence the world of good, those will come in the last 15 mins v the pigs, then we'll all see a new Ched.
Wilder is happy to give him time only 4 months into his contract.
