Midfield
The midfield seemed to lack some strength, as the duo of Xhaka and Guendouzi didn't do enough to stop the attacking plays. Xhaka, as a result, was subbed off for Torreira in both the games. The Swiss player completely looked out of touch and he lost possession a plenty of times and was eventually taken out.
The attacking midfield trio of Mkhitaryan, Ramsey and Ozil could have done much better against Pep's side. Micky looked absolutely clueless about how to gain possession, create and how to start attacks, though he scored a wonderful goal last week against Chelsea. Walker kept him in his pocket for the whole 90 minutes and this is something not good. Micky needs to get back in form otherwise Emery can always start Welbeck or Iwobi in place of him.
