Chelsea made a lot of outgoing transfers during the January transfer window, but the Blues can now reveal a new signing too.
In what was a quiet window for arrivals at Stamford Bridge, Enzo Maresca's side announced on Tuesday that they did bring in one player in fact.
As detailed by Mail Sport on Monday night, the 19-year-old has joined in a deal worth £12million.
The player in question? Saint-Etienne midfielder Mathis Amougou on an eight-year contract.
'I'm very happy,' Amougou said. 'It's an honour for me to sign for such a big club like Chelsea.
