West Ham have taken 17-year-old Norwegian prospect Sander Berge on a week-long trial from Vålerenga, confirms the Scandanavian club.

The Hammers have sent scouts to watch the teenager on several occasions, and have been impressed enough by the defensive midfielder to bring him in on trial with a view to a permanent switch.

According to Norwegian source VG Sporten, there is a “good chance” that Berge will be handed a contract with the Hammers to join them on a permanent basis. He is training this week with the first-team as well as the U21s.

Vålerenga manager Kjetil Rekdal has expressed his admiration for the teenage prodigy, but admits it will be hard to keep him for the long-term.

He is stunningly good. I hope we get to keep him, but there is no guarantee it will be long.

Berge made his debut for Vålerenga against Sandefjord in July 2015 from the bench following a move from second-tier side Asker.

West Ham already have young Norwegian prospect Martin Samuelsen on their books, who has been impressing while on loan at Peterborough this season, which could make Berge’s adjustment to life in England that much easier.
