Caught on camera: Barca substitute bursts into uncontrollable laughter after Xavi yellow card

Xavi received a 41st-minute yellow card in Barca's win at Atleti on Sunday. That decision by the referee had substitute Inigo Martinez beside himself with laughter.

Xavi was complaining about a foul on Lewandowski that wasn't punished when the ref ran towards him and brandished a yellow card. Martinez who couldn't understand the decision yelled out in laughter.

Marcos Alonso couldn't help but smile at Martinez's reaction.

Xavi is now likely to face a three-game ban for the incident.
