Mina has been a bit part player at Everton this season and will be leaving the club in the summer when his contract expires.
Everton are not expected to offer the Colombian a new deal regardless of whether they survive in the Premier League or not.
He has emerged as a big target for Besiktas ahead of the transfer window and the club have been putting in legwork to get a deal over the line soon.
According to Turkish outlet Takvim, serious progress has been made in talks with Besiktas and the player’s representatives.
Besiktas are pushing to work out a deal soon and steal a march over other clubs looking at the centre-back.
Mina is a specific request made by Besiktas coach Senol Gunes, who is a big admirer of the Colombian defender.
The Turkish giants are looking to convince the defender to accept a move to Besiktas in the coming weeks.
