#3. Xhaka, Torreira and Ozil
Granit Xhaka might be error-prone and capable of moments of madness but he is still Arsenal's captain and his ability on the ball is undisputed. His qualities range from cross-field passes to set-piece delivery and long-range shooting. If the Swiss international can eliminate his moments of lack of concentration that lead to poor decisions, he can evolve into one of the top central midfielders in the game.
Xhaka's long range passing ability can be put to good use in releasing the pace of Pierre-Emerick Aubameyang and Nicolas Pepe.
A midfield trio of Ozil, Torreira and Xhaka will prove dominant over many oppositions in the Europa league and could the first alternative in the Premier League because of a balance in attack and defence. Xhaka brings his passing from deep, Ozil brings creativity while Torreira brings his tenacity.
