Former Chelsea and Bayern Munich midfielder Michael Ballack has insisted Mesut Ozil will have to leave Arsenal if he wants to win 'major titles'.

Ballack has claimed he will have a greater chance of adding to his medal collection if he joins German giants - and Arsenal's last 16 Champions League opponents - Bayern Munich.

Ozil has less than 18 months left on his Arsenal contract and has so far failed to sign a new extension to his current deal at the Emirates.
