IF City triggered the buy back, he has to stay with them for a season (on their books anyway) due to limits on how many times a player can move over 12 months IIRC...
So hypothetical talk of buying him back and selling straight to Juve etc can't be done?
Stoke played well today, and I don't mean to take anything away from them, but the fact we were shite and didn't seem bothered, made them look even better.
