Mina, 23, is set to sign a five-year deal at Goodison Park after concluding swift negotiations with the Blaugrana.
Sky Sports News previously reported Manchester United's interest in Mina as they look for a new centre-back, but they are understood to be planning an offer for Leicester's Harry Maguire. However, it seemed that Manchester United had stolen a march on the Toffees as reports filtered through over the weekend that Mina had agreed on personal terms with the Red Devils.
Despite a strong World Cup performance that saw him score three goals in Russian Federation, the defender has been pushed further down the Barca pecking order with the arrival of Clement Lenglet.
If United seriously want to challenge for honours this season, defence is an area they simply must address - and agreeing a deal for Mina would go a long way towards accomplishing those goals.
Barca now have six centre-backs in their squad and only three - Gerard Pique, Samuel Umtiti and new signing Clement Lenglet - appear guaranteed to be at the club when the season begins.
This summer the club have also since signed Clement Lenglet from Sevilla, a move that would make first-team opportunities for Mina even more hard. With Arturo Vidal arriving at Camp Nou, it is all but certain that Yerry Mina will be the player to vacate a non-EU spot.
Yerry Mina has found it hard to continue his progress since joining Barcelona from Palmeiras earlier this year in January.
