Reports in Germany claim that Chelsea are to make a shock move for long time Manchester United target Owen Hargreaves.
The midfielder has made no secret of his desire to leave Bayern, and has been pursued by Sir Alex Ferguson since last summer's World Cup.
Now Bayern Munich claim that the Blues have made secret enquiries about the England midfielder and, worryingly for United, the German club may be keen to listen to offers from the West London side after expressing an interest in signing Arjen Robben.
The German giants are looking for a new winger and had been reported to be making enquiries about French midfielder Frank Ribery - but manager Felix Magath has also admitted an interest in Robben.
"He is a good player, very good dribbler and quick," Magath said.
The Munich chairman Karl-Heinz Rummenigge has also admitted his admiration for the Dutch international.
"He is an interesting player, one that every team would fear to face," he told the press.
Robben has often found himself sidelined this season as Chelsea have struggled to incorporate Andriy Shevchenko and Michael Ballack into their team.
The former PSV Eindhoven player has two years left on his current contract, and has also been linked with a move to Real Madrid.
