Granit Xhaka's arrival at Arsenal will certainly add a bit of steel to the Gunners -- but it will also add to Arsene Wenger's selection problems.
Despite the fact that Mikel Arteta, Tomas Rosicky and Mathieu Flamini will depart this summer, the Switzerland international will make Arsenal's central midfield even more crowded next season, with six players essentially fighting for two spots.
With Jack Wilshere already having made it clear that he doesn't like playing out wide, and the No. 10 spot occupied by Mesut Ozil, it is difficult to see how Wenger will keep everyone happy.
