to cause an upset or win a game you're not expected to win, you need to set up in that manner. Wenger is a manager who has often been guilty of having the same frame of mind and tactics in every game. That will not run here.Its not like its impossible. Causing an upset. We are massive underdogs no doubt- missing players in defense, much worse manager, Özil, Ramsey etc. It can still happen though. Wigan beat City.
We need to sit back a bit and play on the counter, I dont want to see Giroud playing but i know we will
