Barcelona captain Sergio Busquets is a major doubt to face Manchester United next week after the LaLiga leaders confirmed he sprained his ankle against Sevilla.

Busquets was injured inside four minutes of Barca's 3-0 LaLiga win at Camp Nou on Sunday after being caught by Youssef En-Nesyri and was substituted off soon after.

The 34-year-old, who has played in 27 of Barcelona's 31 games this season, underwent a scan on Monday that revealed he has a lateral collateral ligament sprain in his left ankle.

While no official timeline has been given for Busquets' return, the former Spain international is reportedly facing at least two weeks on the sidelines.

That would rule Busquets out of LaLiga games against Villarreal and Cadiz, either side of the first leg of Barca's Europa League knockout play-off round with United on February 16.

Barca travel to Old Trafford the following week, before concluding this month's fixtures with a trip to Almeria in the league.

Busquets' future at Barca beyond this season remains unclear, with head coach Xavi reiterating this week the midfielder will have the final say on whether he stays or leaves.

Xavi's side are now eight points clear at the top of LaLiga, with their routine win against Sevilla coming shortly after Real Madrid's shock 1-0 loss at Real Mallorca.
