Pablo Fornals accuses Sergio Busquets of slap LaLiga Santander - FC Barcelona Incident occurred in Barcelona's victory over Villarreal

Barcelona midfielder Sergio Busquets was involved in a minor altercation with Pablo Fornals on Sunday, in which the Villarreal star accused Busquets of slapping him.

Despite being international teammates with La Roja, the pair clashed on the pitch as they struggled for a loose ball with both individuals on the ground, and video replays appeared to show Barcelona's number five aiming a slap at the 22-year-old.

"He hit me with a slap," Fornals attempted to tell the referee.

No action was taken against the three-time Champions League winner, although shortly after Fornals looked for his revenge and was shown a yellow card for a foul on Busquets.

The match was played with aggression and tension on both sides, perhaps highlighted by the regular incidents between former Espanyol star Gerard Moreno and Barcelona centre-back Gerard Pique.
