Chelsea have agreed terms with Stuttgart for the sale of Dutch defender Khalid Boulahrouz.

Boulahrouz had a disappointing two-year spell with the Blues, failing to establish himself as a regular member of the first-team squad.

He spent the whole of last season on loan in La Liga with Sevilla, but again failed to impress.

However, a number of eye-catching displays at Euro 2008 saw him thrust back into the limelight and he is thought to have cost his new German employers around £4million.

A statement on Chelsea's official website read: "We would like to thank Khalid for his contribution while he was with Chelsea FC and would like to wish him luck at his new club."
