Andre Schurrle has backed Germany teammate Mesut Ozil to improve his performances for Arsenal in the 2014-15 Premier League season.
The 25-year-old became the Gunners' record signing when he joined the club for £42.5m from Real Madrid on transfer deadline day last summer, but made just 25 appearances in his debut season in North London.
The Chelsea winger, who is part of the German World Cup squad alongside Ozil, told talkSPORT: "I'm sure he will be very good next year but I hope not too good because I'm a Chelsea player and I don't want Arsenal to be too good."
Germany face Portugal in their opening World Cup match tomorrow evening.
