I'm not entirely sure how you can say AVB doesn't favour Walker after the amount he's played. There is no evidence of it at all.
Also, not entirely sure he's fallen out with anybody, maybe he just doesn't think a player has been performing well enough. I guess we'll never know though, as we aren't on the training ground and don't know the ins and outs of the club, as it should be.
Edit: didn't Verts play against WBA anyway?
But, but, but, he runs in circles.
