Denayer will do what he has AGREED to do, not what he is TOLD to do. He agreed to sign a new contract with City, only after receiving assurances from the club. If he agreed to the possibility of being loaned out, then there is no problem. If he agreed only because we promised him a chance in the first team, & he doesn't get it, he will try to get a move away.
I would if they treated me like that, & I've been a City fan for 40 odd years, so I'm pretty sure he will be out of the club as fast as possible if we shit on him.
Hopefully whatever we do with Denayer, is what we agreed to do.
