Argentina will be without Manuel Lanzini for the World Cup after the West Ham attacking midfielder suffered a ruptured anterior cruciate ligament in his right knee during a training session.
The 25-year-old had fought his way into the defeated 2014 finalists’ World Cup squad since making his debut as a substitute against Brazil in June 2017, Jorge Sampoli’s first game in charge.
Sampaoli has until 14:00 BST on June 15, 24 hours before Argentina’s opening game against Iceland in Moscow, to call up a replacement for the West Ham favourite.
Lanzini has earned four caps to date and scored his first senior international goal in a 2-0 friendly victory over Italy.
Sampaoli originally named a 35-man provisional squad for Russia and will likely select a replacement from the 12 players he dropped for his final group.
Guido Pizarro, Enzo Perez, Diego Perotti, Leandro Paredes and Rodrigo Battaglia will be hoping to earn a route back into the tournament but it presents the latest headache for the South American giants.
