The Colombian centre-back had reportedly been subject to interest from Manchester United over a permanent move but Everton have swooped in for Mina on the final day of the English transfer window, with the player having his medical in Barcelona in order to push the move through.
Barcelona followed that news with confirmation that Portugal midfielder Andre Gomes would also be moving to the Goodison Park club on a season-long loan.
Chelsea had looked into adding the Brazilian to their squad, and even offered him a contract, but ultimately Bernard was swayed by the chance of more regular football under the guidance of Silva at Everton.
Gomes has always been a fringe player at Barcelona, despite signing for a fee of £31m plus €20m in add-ons in 2016, with only 46 appearances made in La Liga since joining from Valencia.
"For me, it was really good to speak to him because I know how good he is and I feel motivated to work with him and to play for Everton, a great club".
