Sunderland are believed to have accepted bid in the region of £2 million from Swansea City for Joel Asoro.
The 19-year-old has just one year left on his current deal and despite being offered an extension last season, has made it clear to club management that he wishes to move on.
That has seen Swansea move for his services as they undertake an extensive overhaul following their relegation from the Premier League.
New boss Graham Potter is an admirer of the young forward having worked in Sweden for eight years.
He has brought many of his trusted aides for Ostersunds with him to South Wales and they look set to make Asoro one of their first additions.
There has been significant interest in Asoro from across the continent, and the youngster will know have a decision to make on his future.
His departure will underline the need for attacking reinforcements on Wearside, with the club making signings in that department a top priority.
Wahbi Khazri is expected to seal his move to AS Saint-Etienne on Tuesday.
Jack Ross begins his Sunderland tenure with a pre-season clash with Darlington on Tuesday night.
Asoro made 29 appearances across all competitions last season, scoring three goals.
