Lionel Messi scored twice as Barcelona came from 2-0 down to earn a point and draw 2-2 at home to Valencia on Saturday but his exploits may have come at a price.

Barcelona coach Ernesto Valverde admitted the Argentine superstar is a doubt for Wednesday’s Copa del Rey Clasico semi-final at home to Real Madrid after picking up a thigh injury at the Camp Nou.

Messi has been in prolific form of late, scoring 11 in the last nine matches as the champions extended their lead at the top of LaLiga to six points.

The draw ended a sequence of eight successive league victories for Barcelona.
