Sunderland have shown an interest in taking Younes Kaboul from troubled Portsmouth, skysports.com understands.
The 24-year-old central defender has been linked with a move away from Fratton Park as financial problems continue to beset the South Coast club.
Kaboul joined Pompey in 2008 from Tottenham, after just 12 months at White Hart Lane.
Kaboul failed to make the expected impact at Spurs, but he has since excelled at Portsmouth and is now attracting a huge amount of interest.
A host of clubs including French giants Lyon are keeping close tabs on Kaboul, but Sunderland are one of the first to make a move.
Kaboul, who recently scored a last-minute equaliser at the Stadium of Light, is thought to have impressed manager Steve Bruce - who is now considering a move for the giant defender.
Bruce has seen his Sunderland side drop off the pace in the Premier League after a bright start to the season and he looks ready to spend big in January in order to get their campaign back on track.
He is already in talks with Hamburg's Guy Demel and Schalke's Kevin Kuranyi, whilst he has also been strongly linked with Adam Johnson, Charles N'Zogbia and Maynor Figueroa.
