Manchester City have completed a move for highly-rated Argentinian midfielder Claudio Echeverri from River Plate, the Premier League champions have announced.

The 18-year-old, who is understood to have cost City in the region of £12.5million with add-ons, has signed a contract until the summer of 2028, but will remain at River until January next year.

A statement on the club’s official website said: “Manchester City have completed the signing of Argentinian midfielder Claudio Echeverri from River Plate.

“Everyone at Manchester City is looking forward to welcoming Claudio to the club and we wish him the best of luck in his remaining time with River.”

Echeverri will travel the same path as Julian Alvarez, who arrived at the Etihad Stadium from River Plate in 2022.

The teenager, who turned 18 earlier this month, has already made six senior appearances for the Buenos Aries club, which is managed by former City defender Martin Demichelis, and captained Argentina to the semi-finals of the Under-17 World Cup in November and December last year.

Echeverri, who has trained with the senior national team, scored a hat-trick in a 3-0 quarter-final victory over Brazil, but saw his side lose out on penalties to Germany in the last four.

New River Plate head coach Martin Demichelis is in "no doubt" that Argentina will make it to the World Cup final.

Argentina were last crowned world champions when Diego Maradona inspired the 1986 triumph in Mexico, and have since lost in the final at the tournaments in 1990 and 2014.

Demichelis made 51 appearances for his country between 2005 and 2016, appearing at the 2010 and 2014 World Cups in South Africa and Brazil respectively.

The 41-year-old was unveiled as River Plate's new boss on Wednesday and is confident La Albiceleste will make it to the final of Qatar 2022 on December 18.

"We are days away from the start of the World Cup, so I want to wish [Lionel] Scaloni a successful World Cup, to all the players, to the entire squad," the former Manchester City and Bayern Munich defender said.

"A very special mention for the only Argentine player who also ended up joining the squad and who is ours: Franco [Armani], whom we need to support 100 per cent. My congratulations to him.

"I have no doubt that Argentina will play all seven games. I believe that by arriving only seven days before the World Cup, when normally a team is always working for three, four or five weeks, Argentina have the advantage that comes with a very solid base, with good energy, with a very strong emotional determination.

"I have no doubt that Argentina will play all seven games. I wish them all the best."
