Everton want to close a deal for Yerry Mina, of Barcelona, or Manchester United’s Marcos Rojo to resolve their problems in central defence.

Marco Silva, the manager, will look to push through the signing of one of the centre halves to complement the incoming Lucas Digne. The French left back is expected to undergo a medical at Everton in the next 24 hours after a transfer fee in the region of £19 million was agreed with Barcelona.

Everton have been negotiating with Barcelona for the Colombia defender Mina, too, with Rojo an alternative target. The Argentina international did not go on United’s tour to the US owing to an injury sustained at the World Cup, and will be allowed to leave by José Mourinho.
