Chelsea have confirmed the transfer of France international Florent Malouda from Lyon on a four-year contract.
The winger switches to Stamford Bridge for an undisclosed fee although press reports had put the fee at upwards of £13 million (20 million euros).
Malouda will waste no time in joining his new team-mates in Los Angeles where they are currently preparing for the new season.
"The Chelsea squad landed in California to the news that they have a new team-mate," the official Chelsea website reported.
"Florent Malouda successfully completed a medical at Stamford Bridge during the day of Monday and signed a four-year contract."
Jose Mourinho's squad left for Los Angeles on Monday after confirming that a fee had been agreed with the French champions leaving just the medical and agreement on personal terms to seal the deal.
Malouda, 27, was signed by Lyon in 2003 from Guingamp for 4.5m euros having begun his playing career with Chateauroux in 1996. Last season he scored 10 goals as Lyon won the title for the sixth straight time.
He won the first of his 30 international caps in November 2004 and was part of Raymond Domenech's side that made it through to last year's FIFA World Cup final against Italy.
Chelsea's new recruit won the French championship four times with Lyon and was voted the best player in the French first division in 2006/07.
Malouda is Chelsea's latest summer purchase following Steve Sidwell, Claudio Pizarro and Tal Ben Haim.
