Neymar had an unbelievably awkward handshake with referee Ortiz Arias, recreating Thomas Tuchel and Antonio Conte's tense moment after Paris Saint-Germain drew 1-1 with Benfica in the Champions League.
Neymar assisted Lionel Messi's wonder-goal from outside the box to put PSG ahead but the hosts levelled just before half-time when Danilo Pereira scored an own goal.
It ended up being a frustrating night for PSG at the Estadio da Luz and Neymar, along with teammates Marco Verratti and Fabian Ruiz, received yellow cards late on.
The Brazilian was evidently not happy with the standard of refereeing and he had a frosty moment with Arias, who had been the fourth official for the contest.
Neymar shook hands with the Spaniard but footage doing the rounds showed him making a remark to him while covering his mouth.
However, Arias wasn't best pleased with Neymar's behaviour and he kept hold of his hand for longer than he should have.

There were serious Tuchel-Conte vibes, with the exchange harking back to the major beef between the two managers after Chelsea's 2-2 draw with Spurs in August.
Neymar was seen sarcastically putting his thumbs up to Arias before eventually walking away.
The former Barcelona man isn't exactly too fond of UEFA referees, having been booked for doing his trademark celebration earlier this season.

Whenever Neymar finds the net, he put both hands his head and sticks his tongue out.
He did just that in the 3-1 win over Maccabi Haifa but for reasons unclear, referee Daniel Siebert proceeded to book the 30-year-old.

Neymar was completely perplexed by the punishment and tried to plead with the man in the middle, though he wasn't budging.
In response, PSG's No.10 pulled no punches with his assessment of modern football - claiming the game is getting "boring".
As per The Mirror, Neymar said: "I just met the referee and talked to him. He apologized. But now I already have the yellow card. This is a complete lack of respect for the players. The referees have to be there to protect us.
"What happened to me today is very sad. Football is getting boring and we can't celebrate."

PSG have taken seven points from three games in Group H, the same tally as second-placed Benfica.
