Rasmus Hojlund has joined Manchester United on a contract running until June 2028, with the option of a further year, subject to international clearance.
The agreement to recruit him from Atalanta has cost United an initial £64m, plus £8m in add-ons.
At the age of just 20, the striker has scored 27 goals in 87 club appearances, including 10 in Italy for Atalanta last season. Already a senior international, Hojlund has scored six goals in his six appearances for Denmark.
Rasmus Hojlund said: “It is no secret that I have been a fan of this great club since I was a small boy, and I dreamed of walking out at Old Trafford as a Manchester United player.
“I am incredibly excited by this opportunity to turn that dream into a reality, and I am determined to repay the faith that the club has shown in me. It is still early in my career, but I know that I am ready to make this step up and play with this group of world-class players.
“Once I had spoken to the manager, I knew that this environment would be perfect for my development; I am relishing the opportunity to work with one of the best coaches in the world. Under his guidance and support I know that I am capable of achieving great things together with my new teammates at this special club.”
John Murtough, Manchester United Football Director, said: “Rasmus is a truly exceptional talent. He possesses technical and physical attributes which rank him amongst the best players in the world for his age group. Working under Erik ten Hag and his coaches will provide Rasmus with the perfect development platform. Everyone across the club will ensure that he is given the time and all the support required to reach his immense potential.
“Throughout the summer we have acted quickly and decisively to secure our primary targets early in the transfer window. This will ensure that Erik and his coaches have the best opportunity to prepare the squad to push for further success in the exciting campaign ahead.”
