Is there no wifi in Brazil? Was Sanchez and his agent not in Brazil at the same time as Wenger? There is no evidence of any player being signed without Wenger's consent. Just speculation.
I really don't know how Wenger would react if power were to be wrestled from his hands. There was speculation of a rift between him a Steve Bould and it's just speculation but weigh up what's just been posted up about Wenger and delegating tasks to other coaches and there might be something there. I wouldn't rule it out. Wenger has his own way and just look how Bould has morphed into a carbon copy of Pat Rice. He sits on his hands right next to Wenger and says nothing. Just like Pat Rice did. There was talk of Bould not getting much time alone with the defenders, also stuff about us not studying the opposition using video...he's very hands on. If he believe our style of play should be a certain way, I don't know how someone from within the camp can change his way of thinking, especially if they haven't got that much experience either.
Can Gazidis appoint a more experienced coaches to have direct input on what the first team do? I have no idea if that's possible. But he has appointed new youth coaches and a fitness coach so it's possible. But this is worth a read.
