Its annoying it has to be done really but it is a sign of the times. Entitlement of people to demand the answers to things that are not really any of their business. It would be different if Tim had come out and said 'Acun is not backing me' or if players were handing in transfer requests or spouting once they have left about what a terrible club it is but they're not. To me it looks like a simple re-build of a squad that was littered with signings made by an over excited new owner.
A proper manager has come in and been trusted with the job of building from the bottom up again. He knew it was needed and didnt trust Rosenior to do it which is fair enough.
The basis of people spreading rumours about Acun appears to be because he has not spoken in public about City for 2 weeks. Something it was suggested might be better he did more often and let Tan and the Manager do the talking.
The issue is mate. He's set a precedent. He's gone 2 years of being as open as a book and since the Rosenior Q&A he's been radio silent. Now this would have likely been fine had it been business as usual but a few things have happened and those looking for answers aren't getting them from the bloke.
