The young midfielder starred for Argentina in Qatar at the end of last year as they were crowned world champions and he was named the tournament’s best young player by FIFA, completing an outstanding 2022 in which he had caught the eye with a string of impressive performances for Benfica during his debut European campaign.

Upon signing, Fernandez said: ‘I am grateful to Chelsea and its ownership for doing everything they could to make me a part of this project. I’m happy and excited to join the Pride of London, to play in the best league in the world and to compete for the biggest trophies. I can’t wait to play in front of our fans and help my team-mates on and off the pitch.’

As one of the most promising young players in world football, Fernandez will further strengthen our midfield options for this season and the future

Fernandez is primarily a defensive-minded player, but possesses the technical ability to operate as a deep playmaker and the athleticism to move forward and support attacks, leading to him being regarded as a complete midfielder.

The 22-year-old started his career in the River Plate youth system in his homeland, making the breakthrough to senior football by winning continental silverware on loan at Defensa y Justicia, before claiming the league title on his return to River Plate. He was an instant hit when he moved to Benfica last summer, registering 11 goal involvements in his 29 appearances this season.

Todd Boehly, Chelsea chairman, and Behdad Eghbali, co-controlling owner, said: ‘In Enzo we are signing a World Cup-winner and one of the brightest talents in global football. We are excited to add him to Graham’s squad and we are sure he will form an important part of our team going forward. Enzo has demonstrated his ability at the very highest levels so we’re looking forward to seeing what he will do in Chelsea blue!’
