Everton are poised to complete the £6 million signing of Argentina centre-back Ramiro Funes Mori from River Plate this weekend, sources have told ESPN FC.

Mori is flying to England to have a medical ahead of his transfer and will become Everton's fourth signing of the summer after the club agreed a fee and arranged a work permit.

The 24-year-old, who has won one international cap, will add to the Merseysiders' centre-back options after the release of Antolin Alcaraz and Sylvain Distin at the end of last season.
