João Félix becomes new Chelsea player on loan until end of the season
Chelsea have signed Atletico Madrid striker Joao Felix on loan for the rest of the season for a fee of 11 million euros (£9.7m).
Felix has also signed a one-year extension to his Atletico contract until June 2027.
Boss Graham Potter said injuries had "sharpened" Chelsea's focus in their pursuit of the Portugal international, with Christian Pulisic ruled out for a couple of months.
"He's a quality player," said Potter.
"He will make a difference in the final third of the pitch and I'm looking forward to working with him.
"He's young, but still has lots of good experience and it's given us all a bit of a lift.
"I've been aware of the potential deal for a while but the injuries we've had maybe sharpened our focus on it.
"But it's nice to get him here and he's been training today, which is positive for us."
Arsenal and Manchester United had been linked with the 23-year-old, whose wages Chelsea will pay in full until the end of the season as part of the loan deal.
"Chelsea is one of the great teams in the world," said Felix.
" I hope to help the team reach their objectives. I am very, very happy to be here and very excited to play at Stamford Bridge."
He has gone on to score 34 goals in 131 appearances in all competitions, with 18 assists.
Felix was part of the Portugal squad at the World Cup, scoring once in five games as they reached the quarter-finals.
Since then, he has played for Atletico twice, scoring in a 2-0 win against Elche on 29 December before playing 73 minutes in a 1-0 defeat by Barcelona on Sunday.
Felix has scored five goals and provided three assists for Atletico in 20 games this season.
He follows Benoit Badiashile, David Datro Fofana and Andrey Santos in joining Chelsea during the January transfer window, and signs with the club 10th in the Premier League - 10 points adrift of a top-four spot.
They are also out of both cup competitions after losin 4-0 to Manchester City in the FA Cup third round last weekend.
That made it six defeats in nine games in all competitions though boss Graham Potter, who replaced Thomas Tuchel in September, retains the support of the club's board.
