Switzerland international Valon Behrami has joined Italian Serie A club ACF Fiorentina for an undisclosed fee.

The 25-year-old joined West Ham from another Italian top-flight club, SS Lazio, in July 2008.

After an impressive opening season, Behrami suffered a serious knee ligament injury in March 2009 that ruled him out of action for more than six months.

In all, the midfielder made 63 first-team appearances for the Hammers, scoring five goals.

The club would like to thank Behrami for his contribution and wish him every success for the future.
