Yann M'Vila is on Wearside for talks over a season-long loan to Sunderland from Rubin Kazan, according to Sky Sports.
It is believed the France midfielder is keen to move to the Premier League club and could undergo a medical within the next 24 hours.
M'Vila signed for Rubin for £10m from French Ligue 1 side Rennes two-and-a-half years ago.
