People keep saying how Wenger has changed. IMO the problem is he hasn't.
When he came to England his ideas were revolutionary, you didn't have billionaires throwing silly money around.
Football has moved on, Wenger hasn't.
And no, he won't change.
To be honest, even without Billionaires I don't think he'd compete, it's his principles and methods that are flawed these days...not just the fact other clubs have money.
