Cardiff City have announced the signing of Molde midfielder Mats Moller Daehli.
Ole Gunnar Solskjaer had already brought in Magnus Wolff Eikrem from Heerenveen and 18-year-old Norway international Daehli becomes the latest addition.
Solskjaer said: "I am pleased to announce we have signed Mats from Molde, we had some competition and I'm glad to say he has chosen to come to Cardiff instead of going back to where he was before.
"He had talks with United, they had the option to bring him back as part of the deal with Molde but he has decided to come here and that shows his desire to do well here."
Solskjaer believes Daehli can become one of the best midfielders in the Premier League, and revealed he had been a target for his predecessor Malky Mackay.
"He is an outstanding talent. He will be 19 in March, he has just made his debut for Norway so he will give us energy, enthusiasm and good ball control," he said.
"I don't want to liken him to too many players and put pressure on him but he is a central midfielder, he likes to work between the lines and take people on. He is a player of the future. You see the Samir Nasris and David Silvas, in a few years you never know where Mats might end up."
He added: "I know about Mats and all the scouting reports here said to sign Mats Daehli. He has been scouted by the club before and they would have gone in for him anyway apparently.
"They had been watching him before, they went to the Norwegian cup final, they had seen him a few times, but obviously I did not need to go and watch him as I had worked with him close up."
