The Toffees have already gotten in touch with the La Liga giants and have registered their interest in signing him.
The Colombian international joined Barca in the January transfer window from Palmeiras for £10 million, and the Catalan giants have slapped a massive £88 million buyout clause on his head.
Mina has struggled at Barcelona and the club are willing to let him go, mainly on a temporary deal.
With that, he became the first defender to score a goal in each of his first three World Cup matches in the tournament’s history.
At this moment, a season long loan move looks more likely than a permanent exit, and Everton are willing to do such a business.
Mina is a fantastic defender – his arial presence along with his ability on the ball will be beneficial to manager Marco Silva.
