Chelsea have completed the signing of teenage midfielder Andrey Santos from Vasco da Gama.
Sky Sports News revealed earlier in the week that Chelsea had agreed a deal with Vasco to sign the midfielder and that the 18-year-old was undergoing a medical with the Blues.
Santos is the Blues' third January arrival after they confirmed the £35m signing of Monaco defender Benoit Badiashile on Thursday on a seven-and-a-half-year deal and acquired David Datro Fofana from Molde.
Santos ended his Vasco da Gama career with 38 appearances and eight goals.
He said: "It's a very big opportunity for me. This is a big club playing in big competitions like the Premier League, so I am very excited. The players here are so good and I am very happy to be here."
