Everton can confirm the capture of defender Ramiro Funes Mori from River Plate for a fee of £9.5m.
The Argentina international, 24, has passed a medical, agreed personal terms and put pen-to-paper on a five-year contract at Goodison Park.
He has been allocated squad number 25 for the 2015/16 season.
Funes Mori started his professional career with River Plate and went on to make over 100 appearances for the club.
He contributed with 10 goals in that period and last season helped his former team lift the 2015 Copa Libertadores - the South American version of the UEFA Champions League.
The left-footed centre-half’s only cap to date for the senior Argentina national side was against El Salvador earlier this year.
