Good video. I doubt we'll change our shape and will still start as our 10 despite even Wenger admitting he's struggling for confidence. You can only hope that Xhaka coming back will change the dynamic of the team...and I highly doubt that.
He has to move Ozil wide for Iwobi or drop him completely and set up a team that can work hard to win the ball back and counter. For me, 4-3-3 Xhaka, Coquelin and Ox in the middle. They should have the passing range to launch quick counters and they work hard.
Welbeck, Sanchez and Walcott the starting three on attack.
But if Wenger insists on playing Ozil as a number 10, he has to play Elneny and Xhaka.
