Everton have signed Barcelona’s Colombia defender Yerry Mina, 23, for 30.25m euros (£27.19m) along with Mina’s team-mate Andre Gomes on a season-long loan.
The Toffees have also signed Brazilian winger Bernard on a permanent deal.
Barcelona said they reserve the right to buy Mina back, while midfielder Gomes, 25, has cost a £2m loan fee.
“It’s important the club want to fight for something. This is a great opportunity for me,” said Mina.
Mina’s arrival means Everton have spent more than £60m in the past two weeks following the initial £35m arrival of Brazilian winger Richarlison from Watford, a deal that could rise to £50m.
