BERLIN - Brazilian playmaker Diego has not yet decided if he will stay on at Werder Bremen, where he is under contract until 2011, or move to a bigger European club. Diego has been key to his team's UEFA Cup and German Cup semi-final qualifications. And speculation about a possible move abroad at the end of the season has increased in recent weeks, with both Manchester City and Juventus believed to be keen on securing his services. "I have offers from top European clubs," Diego told Sportbild magazine. "(Werder) manager Klaus Allofs is aware of that." He did not specify which clubs but said past interest by Juventus was flattering. "On the one hand, it makes me proud that great clubs like Juventus, for example, have shown an interest. "But I live in reality. All my expectations have been met in Bremen, I am very happy and have a contract until 2011." Diego, 24, said all options were still open, adding: "Either I leave, or stay, or even extend the contract."
