Diaby has so much talent, I'm not ready to give up on him. I think he's been horrendously unlucky with injuries over the years. He needs a season without interruption. If he doesn't find his feet then, maybe it's time to move on. But I think he has the talent to be incredible.
Also agree about the treatment of Wilshere, it's disgusting. Loads of those fouls were clearly with intent to stop him and not get the ball. Fans call Wenger a moaner, but when he see's that regularly you can't help but agree with him about certain players needing protection. I'm certainly not looking forward to the day where somebody let's Wilshere 'know he's there' and it all goes dramatically wrong. Let's face it, it's going to happen, and that's the most depressing part, then people will call it 'part of the game' when it does.
