According to reports, Manchester United are in serious negotiations with Filling, who is available for a relatively low transfer fee of around €3 million. Bundesliga clubs are also interested in signing the young forward.

Filling is a tall and talented player, standing at just over 6 feet at 16 years old. His height and skill have caught the attention of Manchester United, who are speeding up their negotiations after interest from Tottenham was dropped. United defender Victor Lindelof also has a connection to Filling, as he came through the Vasteras youth system.
