FC Copenhagen youth coach Alfred Johansson is confident Rasmus Hojlund can succeed with Manchester United.
Hojlund came through the youth system at FCK.
Johansson told the Manchester Evening News: "It was 2017 when he joined the club's Under-15s and I was head coach of the Under-13s at the time. I didn't work personally with him, but obviously, I watched the games," he said.
"He's always been a confident player, hard-working and very ambitious. At certain moments in the academy, his self-confidence was naturally lower and at other moments higher, but generally speaking, it was very high for Rasmus.
"I remember my first impression of him was a physically big striker. He was one of those guys who grew a lot in a short period of time, so he wasn't always in the best control of his body, but you could see straight away he was very strong.
"He was pretty explosive in the way he was built on the pitch and it was a challenge to control that power."
Johansson added: "Back then, ball control was definitely not one of his main attributes. I would say definitely the physicality was a strong point and he's always been very eager to finish, so he always liked to practice in training.
"We know from our statistics at Copenhagen that many players that reach U15 level, especially to Under-17 and U19, end up getting a professional contract, but did we expect to see Rasmus at Manchester United at this early stage?
"Of course you have to be a little bit surprised. You can see the young guys who are performing, but to say they're going to sign for Man United for that amount of money, I think it would be arrogant to say you can see that, at that particular point."
