According to a report in the Chronicle, Tottenham Hotspur are looking for £3 million for defender DeAndre Yedlin.
Sunderland have already made enquiries, as they look to bring Yedlin back to the Stadium of Light next season.
Yedlin was on loan with the Black Cats last term, and he grew in importance to the North East side as the campaign progressed.
The USA international was in fine form towards the back end of the term, as he helped Sunderland avoid the drop.
The Black Cats are now keen to bring him back to Wearside, but a deal is still some way away from completion.
Sunderland are apparently keen to bring Yedlin back on loan for next season, with a view to making the move permanent at the end of the campaign.
Spurs, however, seem more keen to allow the defender to leave on a permanent transfer.
Yedlin does not appear to have a first-team future at Tottenham, with both Kieran Trippier and Kyle Walker ahead of him in the pecking order for places.
