Real Madrid star Cristiano Ronaldo was bristling after his penalty claim was denied against Barcelona.
Ronaldo was furious with not only the ref's call, but Sergio Busquets' mocking in the aftermath of the incident.
The Portuguese immediately went to Barca captain Carles Puyol at the final whistle to make his feelings known before heading to the away dressing room.
Ronaldo refused to comment publicly, says AS, but made it clear to friends and family how upset he was with the decision.
