I don't think Arsenal have a weakness as such, but they're not a team of supermen either. They're much better than last year when teams could ruffle them a bit and they've added a bit more X-Factor. They are genuine title contenders now & I wouldn't mind seeing them do it, but ultimately I think City will win it.
No way Martinez will approach this differently, he'll set up roughly the same.
Arsenal could well underestimate Everton here though, a one off game like this will probably be decided by one goal. For me, the way to beat them is to run at them through the middle. we certainly have the players to do that.
1-2 Everton
