The Swiss international, Arsenal's fourth most expensive signing at £33.8million, was left on the bench for his new side's first Premier League game of the season, a 4-3 home loss to Liverpool, but started each of the following two games.
“I have not come to Arsenal to sit on the bench or even in the grandstand," he told Berner Oberlander. “But I'm not 30, I'll be 24 at the end of September. I've moved to a club and a coach that can develop me.
“I think at Arsenal I can improve my speed and power. Because I realize now that I'm not at a hundred per cent of what is possible there. [Understanding] this too is an advancement."
