The Premier League club offered €24m for the centre-back who scored three times during the South Americans run to the last sixteen, including a last-minute equaliser against England in Moscow.
His form during the group stage impressed newly-appointed Everton boss Marco Silva and the Merseysiders moved swiftly once Colombia’s run was over.
Mina, 23, moved to the Camp Nou in January from Palmeiras in a €11.8m deal. Contracted until 2023 and with a release clause of €100m, the Blaugrana are keen to cash-in on the player this summer.
Talks already took place with Everton with the Toffees preferring a permanent deal instead of the loan Barcelona proposed. If a deal is to succeed, it’s understood that a ‘buy-back clause’ will be inserted in the sale contract.
Mina made only made six appearances as the Catalans romped to the La Liga title and Barcelona’s attitude suggests they are far from convinced the relatively inexperienced defender is going to make the grade in Les Corts.
The two clubs are due to meet again next week to push the deal through with Mina expected to move to Goodison Park within the next fortnight.
