Barcelona have confirmed Lamine Yamal suffered a left hamstring strain while on international duty with Spain.

The 17-year-old limped off in the 93rd minute of their Nations League clash against Denmark on Saturday before returning to Barcelona to undergo further tests.

He was one of La Roja's brightest players in the 1-0 victory, having five of their 25 shots, the most by a Spain player in the competition this season.

However, he is now set for an undetermined spell on the sidelines, though he is likely to miss their LaLiga match against Sevilla on Sunday.

Yamal has started 11 of Barca's 12 games in all competitions so far, and Hansi Flick will be hoping he is not set to endure a long layoff, with matches against Bayern Munich in the Champions League and Real Madrid in the league also coming up next week.

If he is not involved, it would prove a huge blow for Barcelona. This season, Yamal and Robert Lewandowski have been involved in 21 Barcelona goals in LaLiga, the best goalscoring duo of any club in the big five European Leagues.

"Tests carried out this morning on first team player Lamine Yamal have confirmed that he has a left hamstring strain. His return to training will be determined by his recovery time," Barcelona said in a statement on social media.

Barcelona return to league action this weekend when they welcome Sevilla to the Camp Nou on Sunday.
