Mina and Gomes are expected to undergo their medicals in Barcelona as there is little time for them to travel to England to complete the formalities of the transfer.
Everton have agreed a deal to sign Yerry Mina, the defender leaving Barcelona after an unhappy six-month spell in La Liga.
Yerry Mina and Andre Gomes, recruits from Barcelona, are not yet ready and neither is Brazilian winger Bernard, who arrived on a free transfer.
Barcelona confirmed the deal for Gomes that will see Everton pay the Portugal worldwide midfielder's wages for the full season, while also paying a loan fee of £2m (€2.25m).
Bernard was first to sign on deadline day after receiving a work permit to move to the Premier League following five seasons at Shakhtar Donetsk.
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.
"I spoke to Lucas and he told me all about the Club, which also made me keen to come here".
But I was also convinced Everton could improve me and that I would be able to show my best as a player here'.
"The manager made me feel confident about playing here".
"We were dealing with Barcelona with [the transfer of Yerry] Mina, and I know the player very well".
