Mikkel Diskerud is attracting interest from Portland Timbers according to his father and agent.
The 22-year old Norway-born USA international is currently out of contract at Rosenborg where he is considering the offer of an extension.
Diskerud is also being tracked by Austrian club Rapid Vienna but his father, Paal, has revealed that the Timbers are very keen.
"(Timbers head coach) Caleb Porter has contacted Mix and asked him to consider joining him on his move to the Portland Timbers, if possible," Paal Diskerud told MLSsoccer.com.
"Representatives of the league ownership in MLS, including Portland, and Mix (Mikkel) have not at this point attempted to contractually bind each other.
"Mix believes in Mr. Porter's potential to build balanced teams along the modern – and, in the opinion of Mix – most fun styles of play.
"The short-term goal of Mix is to be able to co-contribute in moving the USMNT further up the FIFA World Ranking table.
“Mix does know, that until now, it has been uncommon for young players of European leagues, educated in European leagues, to go play professionally in USA and Canada early on in their careers.
"[He] is very honored that both have asked him to help along and promote the world's overall biggest sport in the country he has chosen to represent internationally."
