Brazil forward Matheus Cunha said his “dream” had become a reality after completing a £63m move to Manchester United.
United activated a release clause in Cunha’s Wolves contract this month.
The deal, which was subject to a visa and a medical, has now been completed.
Cunha has signed a five-year contract, with the option of a further 12 months.
“It is hard to put into words my feelings about becoming a Manchester United player,” he said.
