Sunderland have reopened talks with Tottenham over a permanent move for defender Kevin Danso.
BBC Sport revealed on Friday night that Sunderland had a loan offer rejected by Spurs for the Austria international.
But the Black Cats have returned to the table and opened discussions over a permanent offer for Danso.
Personal terms are not said to be an issue for Danso if the clubs agree a fee.
Club-to-club talks are progressing but as of yet there is no agreement.
Tottenham are likely to require a replacement before sanctioning an exit for Danso, with manager Roberto De Zerbi wanting that player to have Premier League experience.
Danso was signed on loan from Lens in January 2025 and the deal was made permanent later that year with Spurs paying the French club £20.9m.
Sunderland are also interested in signing Lyon winger Malick Fofana after previously making an offer for Marseille's Igor Paixao.
Fofana, 21, is open to a move to the Stadium of Light after being linked with a switch to Roma earlier this summer.
However, the Belgian is just one of a number of options being considered by Sunderland. Paixao has been the subject of a formal bid, while the Black Cats have also been linked with Manchester City winger Jack Grealish.
Grealish is understood to be prioritising a move to Everton, despite attracting interest from his boyhood club Aston Villa.
Sunderland are also keen on signing a centre-back before Tuesday's transfer deadline.
