Andrey Santos has said it is a dream to play for Manchester United, after his £50 million move from Chelsea was announced on Monday.
The Red Devils will pay a guaranteed £48m payment plus £2m in add-ons.
Chelsea, however, retain a 10 per cent sell-on clause.
The 22-year-old joined Chelsea from Vasco da Gama in 2023 and spent time on loan at Nottingham Forest and Chelsea’s sister club Strasbourg.
Santos said: “Everything about Manchester United is special; it is an incredible feeling to join a club that some of my biggest idols have represented.
“As a midfielder, I am really excited to have the opportunity to learn from Michael Carrick. He is the perfect coach to help me take the next step in my career and push to achieve my dreams.
“Everybody told me about how ambitious the club is and the amazing environment that has been created here. I know just how strong the squad is and I cannot wait to fight together to compete for the biggest trophies.”
