Barcelona boss Gerardo Martino said he will have to wait to see how serious Lionel Messi's latest hamstring injury is after the Argentine limped off after just 20 minutes of Barca's 4-1 win over Real Betis on Sunday.

It was the third time this season that Messi has been forced off with a muscular problem, following hamstring and thigh injuries.

However, Martino insisted the four-time World Player of the Year's injury troubles were not related as it is his left hamstring that forced him to be replaced in Seville, while his previous injuries this season had been to his right leg.
