With PSG 2-1 up, TV cameras showed the French giants trying to keep possession before Presnel Kimpembe played a pass forward to Neymar.
But the Brazilian superstar wasn’t looking. He was instead trying to get the crowd to crank up the volume, throwing both hands in the air as play went on behind him.
The ball then rolled past Neymar, who stopped his pleas to supporters and instead turned his back on play again in disbelief.
Not that it mattered as Liverpool endured horrible travel sickness as they went down to defeat.
Still, the 2-1 loss – their third away defeat in the Champions League this season – did not kill off their hopes of progressing to the knockout stages of the competition.
They now have to win 1-0 or by two clear goals when they take on Napoli at Anfield on December 11.
The Reds were undone by an early blitz from superstar front three Neymar, Kylian Mbappe and Edinson Cavani, with the Brazilian scoring a fine counter-attacking goal after full-back Juan Bernat had opened the scoring.
A penalty just before half-time from James Milner could not drag Liverpool back into the game, but a decent second-half display will give them hope they can still progress.
Captain Jordan Henderson said: “We’re disappointed. We feel we’re good enough to come here and win. It wasn’t our night but we tried to keep pushing for the equaliser. We kept going and kept fighting and now we just need to keep our hopes up with a win at Anfield.
“We just need to get through that game against Napoli now. It’s still in our hands.”
Marco Verratti was lucky to escape a red card for a shocking challenge on Joe Gomez.
Henderson said: “It looked quite high but I’m not really sure. In the moment it is fast and that is football. I’m sure we made a few as well.”
While angry Liverpool manager Jurgen Klopp criticised the refereeing of Polish official Szymon Marciniak for making his side look like “butchers”,
The Reds boss was unhappy with the hosts’ play-acting and highlighted Neymar’s role as the Ligue 1 club consigned Liverpool to a third away defeat in Group C.
“The number of interruptions in that game was just not cool,” said the German.
“Two times in a row we won the Fair Play award in England and tonight we look like butchers after the yellow cards we had.
“It was clever of PSG, especially Neymar, but a lot of other players went down like it was really something serious and we were not that calm any more.
“We were aggressive, and unfortunately negative aggression doesn’t help in football, we got rather frustrated and angry.
“But we have to deal with it, that’s our job. If the ref lets that happen then we have to deal with it.”
