I think Wenger has realised he is skating on thin ice with the supporters, and his pathetic attitude towards transfer windows has made a lot of supporters turn against him.
That, and finishing fifth, behind spurs, not being in the CL and watching all our rivals qualify for it, as well as his only world class players wanting to leave.
Saying that, I'm not sure he has acted that quickly.
He has bought Lacazette, who is a decent signing but a few seasons too late, and he might buy Lemar, who is an inferior version of Sanchez.
For me that represents a poor transfer window because if we couldn't get a top four place last season with Sanchez, I don't see how we are going to do it without him next season.
Having a massive overhaul of the first team, with at least three world class players coming in, and losing two or three of our under performers might have convinced me he's changed.
But that isn't going to happen.
