Everton have completed the signing of a defender Ramiro Funes Mori from River Plate for a fee of £9.5 million.
The Argentina defender has signed a a five-year contract at Goodison Park and will wear the shirt number 25 for the 2015/16 season.
The 24-year-old agreed terms and passed a medical last week but delays in paperwork and securing a work permit delayed the transfer going through.
Who is Funes Mori?
He joined River Plate in 2008 as a youth player, before progressing to the senior team in 2011 and made 108 appearances, scoring 10 goals. Mori has played a big part in River Plate's success over recent years.
The Argentine was part of the team that were promoted from Argentina's second tier and helped River Plate lift the 2015 Copa Libertadores- the South American version of the UEFA Champions League.
The left-footed centre-half has one international cap for Argentina, making his debut in March in Argentina's 2-0 victory against El Salvador in a friendly.
"I'll give everything"- Mori
Mori told the club website that he didn't have to "think twice" after hearing about Everton's interest and added that he is "very happy" to finally sign for the Toffees after delays in the transfer going through.
He said that he is the type of player who likes to "work hard in every training session and game" and added that he will "give everything" to be a success at Goodison Park.
The 24-year-old said that he knows Everton have "a lot of history" and that "a lot of good players have come from Everton" and hopes that he "can stay here for a long time" and "grow as a player."
He also said that he has already been made to feel more than welcome at Everton and already feels "comfortable" in his new surroundings.
What will he bring to the side?
Mori strengthens Everton's defensive options as, after Sylvain Distin and Antolin Alcarez were released this summer and will provide much-needed competition and cover for Phil Jagielka and John Stones.
Martinez has been looking to bring a left-footed defender to Goodison Park and Mori fits that profile.
The 24-year-old also has good aerial ability in both boxes and scored a number of crucial goals for River Plate.
