Neymar is clearly frustrated at the moment.
Barcelona's season is faltering. They are out of the Champions League and the Spanish title race is wide open. Neymar's form has not been good over the last month. He has not scored in that period - a five-game goal drought.
During Sunday's 2-1 defeat to Valencia at the Camp Nou, he slapped Dani Parejo as the Valencia players celebrated victory. Spanish media later reported that, in the tunnel, he threw a water bottle at Antonio Barragan.
It wasn't just opposition players who felt the wrath of the Brazilian. One of his teammates did also.
Spanish show 'El Dia Despues' regularly interprets the words of La Liga players through use of a lip reader. So notorious is the show, players often cover their mouths for fear of making an appearance on the show.
Such was Neymar's irritation with Jordi Alba during Sunday's game, this was something which slipped his mind. After failing to receive a pass from the Spanish international left-back, he gave Alba a piece of his mind.
Go fuck yourself! What? What? You got a problem?
Here's the video.
