The Dinamo Moscow stopper, who was in the side which lost to Celtic on Wednesday, is said to be keen on a move to England.
And the 26 year-old has been linked with a switch to four different Premier League sides, including Villa and Arsenal.
Fernandez has an EU citizenship and is regarded very highly by a host of European sides.
He is a firm fans favourite in Moscow and although it would be difficult for him to leave a club with which he has a strong affinity, the lure of Premier League football would surely sway him.
A fee of around £7m may be enough to persuade Dinamo to part with the player and it now remains to be seen whether English interest materialises.
