Chelsea have signed Dutch international Boudewijn Zenden from Barcelona for £7.5m.
The Blues announced that the 24-year-old has signed a four-year contract at a press conference in Stamford Bridge this afternoon.
Zenden is Chelsea's fourth signing this summer following the arrival of William Gallas, Emmanuel Petit and Frank Lampard.
The Dutchman had been surplus to requirements at the Nou Camp after compatriot Marc Overmars took over his place on the left wing.
