AMSTERDAM – Rosenborg have closed a deal to acquire Stabæk midfielder Mikkel Diskerud, officially unveiling the fresh recruit on Thursday evening.

The 21-year-old US international inked a contract through year's end, allowing him the possibility of becoming a free agent again during the January transfer window. MLSsoccer.com has learned that the transfer fee paid by Rosenborg fell a shade less than $1 million.

"This feels a little special," Diskerud told the club website. "Rosenborg has been the best team in Norway and has been there for decades. It will be an honor to play for a club that wants to [raise the trophy]."

Rosenborg stand third, six points behind leaders Strømsgodset, who finished second in the race to land Diskerud. Tippeligaen side Brann and a Danish Superliga club had dropped out of the running for his services earlier in the week.

It remains to be seen if Diskerud – set to become the second American to play for Rosenborg, following current D.C. United defender Robbie Russell – will suit up for the Troll Kids at Sogndal on Sunday.

On Friday afternoon, Diskerud and his new employers will learn their Europa League playoff-round opponent.
