The 23-year-old Argentina international won’t be present for the team’s last six 2023–24 Premier League games.
However, he might aim to return in time for the June 20–21 Copa America.
At the conclusion of the 2023 winter transfer window, Fernandez signed a contract with Chelsea after leaving Benfica for a British record £107 million.
Following his nation’s 2022 World Cup victory, he was awarded young player of the tournament.
Despite the club’s challenging season, Fernandez has made 40 appearances for the Blues and scored seven goals.
