Sunderland are being kept updated about Momo Sissoko's situation with the former Liverpool midfielder looking for a Premier League return.
The 31-year-old is hoping to ply his trade in England again after spending two months out in India with Pune City.
David Moyes does not have money to spend this month and has held discussions about potentially landing Sissoko.
The ex-Juventus man is a free agent after leaving Pune as a marquee player and could provide the Black Cats with additional strength in depth during their relegation fight.
