Barcelona's Neymar Jr. is at the centre of a headbutt storm after a 20th minute incident during Sunday's La Liga fixture against Valencia.
The Barca winger appeared to strike Valencia CF's Nicolas Otamendi with his head after being taken to ground in the penalty area.
Both players went unpunished for the altercation, despite Otamendi flying backwards with his hands over his face in a gracious dive. The Argentine defender's theatrics were probably a bit too delayed to get his opponent sent off, but the resulting argument between both teams saw Barragan and Piqué booked.
The hotly contested game also saw a grumpy Valencia fan banned from the stadium after throwing a water bottle at Lionel Messi after Sergio Busquets' game-winning goal in the 94th minute. The last gasp goal helped Barca close the gap with Real Madrid at the top of the table.
