Chelsea completed the signing of Manchester United outcast Alejandro Garnacho on Saturday for a reported £40 million fee ($54 million).
The Argentine international, 21, has signed a seven-year deal with the world champions.
Garnacho was in attendance at Stamford Bridge to watch the Blues go top of the Premier League with a 2-0 win over Fulham on Saturday.
“It’s an incredible moment for my family and I to join this great club. I can’t wait to get started,” said Garnacho.
“I watched the Club World Cup and to join the world champions is special – we’re the best team in the world! It’s amazing to be here and I’m very happy.”
Garnacho scored 26 times in 144 appearances for United, including in the Red Devils 2-1 FA Cup final win over Manchester City in 2024.
However, he fell out of favour under Ruben Amorim at Old Trafford and had been part of a small group, also including Antony and Jadon Sancho, excluded from first team training with the rest of the squad this season.
Garnacho’s arrival takes Chelsea’s spending in this window beyond £250 million.
Joao Pedro, Liam Delap, Estevao and Jamie Gittens have also added to Enzo Maresca’s attacking options.
However, a hamstring injury suffered by Delap against Fulham could scupper Nicolas Jackson’s departure on loan to Bayern Munich.
