It looks like the £42.5m man is enjoying his new life at the Emirates with fellow Germans which can only be a good sign for the Gunners. Arsenal stand at the top of the table leading Spurs by two points after 6 games. Arsenal host Napoli in the Champions League second round fixtures later tomorrow which will see the arrival of their summer target Gonzalo Higuain spear heading the Serie A side?s attack.
