Cunha has a £62.5m release clause at Wolves. Man United have fully met the conditions in the striker's contract. The 26-year-old Brazilian striker signed a contract with Man United until June 2030.
On his debut for the Old Trafford team, Matheus Cunha shared: "It's hard to describe my feelings as a Man United player.
Since I was a child in Brazil, I have watched Premier League matches at my grandmother's house on TV. Man United has always been the English team I have loved the most.
I dreamed of one day being able to wear a red shirt. I would like to thank my family and all those who have helped me make that dream come true.
I am very eager to enter the pre-season, get acquainted with my new teammates and prepare for the upcoming season.
Now, my entire focus is on working hard to be an important part of the team and helping the club return to the top."
Meanwhile, Director of Football Jason Wilcox said that Man United was delighted to have completed this deal early in the transfer window.
Cunha possesses all the qualities the "Red Devils" are looking for when building a strong, dynamic, attractive team capable of competing for the biggest titles.
