Arsenal's record signing Mesut Ozil needs to be more consistent, says Invincible goalkeeper Jens Lehmann.

The 45-year-old, who played every game as the Gunners went unbeaten on their way to the 2003-04 Premier League title, says that the £42.5million playmaker "can be fantatic" has to do more when Arsenal play their main rivals.

"Everyone knows he can be a fantastic player. But you need to be a fantastic player in the big games," Lehmann told The Sun.

"You don't need to be a fantastic player in the small games and mediocre player in the big games.

"He can definitely do that but now he must prove it. You need to know how to think and how to programme yourself."

In his two seasons at the club Ozil has only scored one goal and added two assists in 11 matches against Chelsea, Manchester United, Manchester City and Liverpool, and was singled out for criticism by Thierry Henry after the 0-0 draw with the Blues that effectively handed them the title.

Lehmann added: "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."
