Krasnodar have reportedly approached Swansea City to enquire about the availability of Federico Fernandez.
The Russian outfit have contacted the Swans to make their interest in the Argentina international known but are yet to table a formal bid, according to WalesOnline.
Fernandez is one of several Swansea players linked with a summer exit due to the club's relegation from the Premier League last season.
The Welsh club could also lose Alfie Mawson and Kyle Bartley, with both players said to have attracted interest from teams in England's top two divisions.
Meanwhile, manager Graham Potter is yet to make his first signing since taking charge.
