Liverpool legend Jamie Carragher says it's time for Mesut Ozil to step up at Arsenal.

The Gunners go to Anfield today.

Carragher wrote in the Daily Mail: "I've been a fan of his since I saw him at the World Cup finals in 2010 and I was genuinely excited about the prospect of the Germany midfielder displaying his skills in the Barclays Premier League.

"With four goals and eight assists, he has had a good start. But that is all it has been.

"Over the next fortnight, Arsene Wenger will want Ozil to show why he invested £42million in him; when you spend world-class prices on world-class talent, you want to see them produce in the games that matter."
