London: Former Germany goalkeeper Jens Lehmann says his compatriot Mesut Ozil needs to become more influential and play a pivotal role for the Premier League club in high-voltage games.
Ozil joined Arsenal from Spanish giants Real Madrid two summers ago and has somehow managed to adapt himself with the rigorous league. The 26-year-old scored five goals and provided nine assists last season.
"Everyone knows he can be a fantastic player. But you need to be a fantastic player in the big games, you don't need to be a fantastic player in the small games and mediocre player in the big games," Lehmann was quoted as saying by goal.com on Sunday.
The former Arsenal goalie added that he does not doubt the ability of the talented left-footed player but believes time has come to prove his worth.
"He can definitely do that but now he must prove it. You need to know how to think and how to programme yourself. Of course he can improve. You can't get better on the day that you retire from football but you can every day before that," he said.
