Not sure I can see him going to Bayern if one of the alleged reasons is that his wife/girlfriend is homesick and wants to return to the north of England. Personally, I think he will be staying and will work out his issues with Poch unless City make a crazy bid and Poch evaluates that and feels that the money on offer combined with the disruption of keeping him is a better deal. I don't doubt that something has definitely gone on and if it was right for him in all aspects that Walker push to leave but I do honestly think he has an affection for the club that would make it more of a last resort than it would perhaps for other players within the squad.
