Should Arsenal fans worry after Mustafi dropped for Germany?

I must admit that I am getting a bit worried about the German international centre back signed by Arsenal last summer, as Shkodran Mustafi seems at times to be going backwards in his development as a top class player. Those fears were not helped last night by the fact he was dropped from the first team by Joachim Low last night as Germany cruised past Mexico into the final of the Confederations Cup.

Maybe I am making too much of this and Mustafi will be back as one of the first names on the Arsenal team sheet of Arsene Wenger when the new season starts, but I cannot help but feel that he has lost his way a bit of late. When he first came to north London the German looked the real deal and we were all talking about him and Laurent Koscielny being the best defensive pairing in the EPL.

In the latter stages of the season, however, after a fair few costly errors and rash decisions, many of us were not too fussed when Mustafi was not in the side and both Rob holding and Per Mertesacker looked more solid when Wenger gave them a chance. Now we have Calum Chambers fighting for a spot as well, so do Arsenal and Mustafi have a problem to solve?
