Barcelona forward Ansu Fati has been ruled out for about four months after having knee surgery.
The 18-year-old was operated on after suffering an injury to the internal meniscus of his left knee against Real Betis.
The Spain international was substituted during half-time of the 5-2 win on Saturday.
Fati has played 10 games for Barcelona this season, scoring five goals and providing two assists.
He broke a 95-year national record to become Spain’s youngest goalscorer at the age of 17 years and 311 days with a strike against Ukraine in September.
