Sunderland are battling with AC Milan and Sporting Lisbon to sign two Swedish teenagers, Sky Sports understands.
Robert Mirosavic and Linus Wahlqvist have spent time on trial on Wearside in recent weeks.
15-year-old central defender Wahlqvist has emerged as one of the most highly-rated youngsters in Scandinavia.
He has impressed during training stints with the Black Cats, but Italian giants Milan are also keen.
Now Sunderland are ready to battle it out with the Serie A giants, with the player believed to be keen on a move to the North East having been impressed with the facilities at the Academy of Light.
And Wahlqvist is not the only youngster who could soon be finalising a move as the Wearsiders are still interested in Sweden Under 17 captain Mirosavic.
The Helsingborgs forward has spent two separate trials with Sunderland and has impressed their youth coaches.
Barcelona, Real Madrid, Arsenal and Chelsea also have an interest in the 17-year-old.
However, Sporting have moved into pole position in recent weeks and they are confident of finalising a deal for him on a long-term contract.
