Former Germany captain Michael Ballack says Arsenal midfielder Mesut Ozil has to join Bayern Munich if he wants to win major trophies.
Ozil has not yet signed a new deal with Gunners despite only having 18 months left on his current contract.
With the London club set to miss out on winning the Premier League yet again, they are 12 points behind table-toppers Chelsea with only 14 games remaining, Ballack has suggested that Ozil consider a move back to his home country.
Ballack told Bild: "Mesut is an amazing player. He knows that he is one of the undisputed stars at Arsenal. A lot of clubs would love to have him.
"He lives in London, one of the most beautiful cities ever. To this end, Arsenal is a club that has an incredible impact on the world.
"If you are a top player in England, the cult around you is bigger than in Germany. You are treated more respectfully, especially. These are all reasons for an extension.
"But if he wants to win a major title, he has a bigger chance to achieve that at Bayern."
