Chelsea have signed Egypt midfielder Mohamed Salah from Swiss champions Basel for a fee in the region of £11m.
The 21-year-old, who will wear the number 15 shirt, has signed a five-and-a-half year deal.
“I’m very happy to sign for Chelsea. I hope I can make the Chelsea supporters happy and have a good career at the club for many years,” said Salah.
Salah is Chelsea manager Jose Mourinho’s third signing in the January transfer window after the arrivals of Nemanja Matic and Bertrand Traore. His arrival comes at Stamford Bridge after Chelsea sold midfielder Juan Mata to Manchester United for £37.1m on Saturday.
Chelsea’s Premier League rivals Liverpool were also interested in signing Salah and had held talks with Basel.
