Barcelona pair Gerard Pique and Dani Alves clashed during their Copa victory over Real Betis.
The defensive duo almost came to blows halfway through the first-half after Betis striker Ruben Castro had escaped their attentions and threatened to score.
Pique accused Alves of being at fault and the heated discussion last over 15 seconds with the Spaniard grabbing Alves' arms.
In the end, the row did not spill over into fisticuffs and Barca went on to record a 5-0 victory.
