Manchester United have competed the signing of forward Matheus Cunha from Wolverhampton Wanderers.
United had announced on June 1 they had agreed a deal for the player pending visa and registration processes.
ESPN previously reported that United triggered the £62.5 million ($83.5m) transfer clause in the Brazil international’s contract at Molineux.
United agreed to pay the fee over two years after initially trying to negotiate a deal that would have seen the money paid over four or five years, sources said.
“It is hard to put into words my feelings about becoming a Manchester United player,” Cunha said in a statement released on Thursday.
“Ever since I was a child in Brazil watching Premier League games on TV at my grandmother’s house, United was my favourite English team and I dreamed of wearing the red shirt. I want to thank my family and everyone who has helped me make that dream a reality.
“I can’t wait for the start of pre-season to get to know my teammates and prepare for the season ahead. All my focus is now on working hard to become a valuable part of the team, and helping get this club back to the top.”
