Only thing i'd add is, a proper manager finds a way to incorporate Santi and Ozil in the first 11. You dont leave quality like that on your bench. The way to accomplish that though, is you give your team the proper backbone so those kind of players have the ability to express themselves freely. Look in the league, Chelsea is able to put Oscar, Hazard, and Willian in their lineups without missing a beat. Santi Cazorla is not a worse player, or significantly slower player than Willian. Yet Willian pops up all over the pitch and is willing to make those forward runs and support his fullback because he has confidence that his back 4 and holding midfield won't do stupid shyt to cause chances. I feel dirty for comparing us to Chelsea
but its clear as day our issues are in the central midfield. A Gilberto Silva type player gives a manger so much tactical flexibility.
EDIT: oh ya...i forgot to mention we are playing a tree up front
At least the old Arsenal would give up 3 and score 4.
