Chelsea have announced that 22-year-old midfielder Gael Kakuta has joined Lazio on loan until the end of the season.
The France youth international will join a Lazio side who are battling poor form and are 10th in the Serie A table.
Kakuta, who joined the Stamford Bridge outfit from Lens in 2007, has spent the last season and a half on loan at Vitesse.
The Eredivisie club, who Chelsea have a partnership with and loan several players to, have helped Kakuta make 40 appearances in his stint at the club.
The loan move will be the fifth of Kakuta's career, with his time at Vitesse preceded by stints at Fulham, Bolton and Dijon.
Kakuta has made just 16 senior appearances for Chelsea.
