Liverpool boss Jurgen Klopp was duped into thinking that Mohamed Salah had converted his penalty as he was judging the result of the spot-kick by the reaction from supporters. However, the Egyptian skewed his effort wide and the travelling Arsenal fans tricked Klopp into thinking his side had drawn level at Anfield.
Liverpool had the chance to tie the game at 2-2 when Rob Holding bundled over Diogo Jota inside the box following a corner, as Salah stepped up but placed his penalty wide of the left post - much to the jubilation of the Arsenal Players and supporters.
Several Gunners stars could be seen taunting Salah as the forward buried his face into his short to avoid the reality of his miss, as Aaron Ramsdale especially was spotted laughing at the Liverpool man.
Manchester United icon Gary Neville, on commentary for the game, noticed the Arsenal stopper's actions towards Salah as he explained the penalty miss. "You sometimes get that little bit of luck on your way to a title, and Arsenal have just had it," Neville told Sky Sports. "Holding’s just had it, Ramsdale screams with delight. He just passes it past the post, there’s nothing else you can say."
Klopp routinely does not watch his Players take penalties, but this time his nerves came back to bite him as he was spotted smiling as he turned around after being convinced by Arsenal fans that Liverpool had scored.
When he faced the pitch and was made aware of the reality that the Reds were still losing to the Premier League table-toppers, Klopp held out his hands in confusion because none of his Players were celebrating with him.
Earlier in the game, Gabriel Martinelli gave Arsenal the lead when two errors by Andrew Robertson and Virgil van Dijk allowed the Brazilian to ghost into an attacking position before poking the ball past Alisson.
The visitors raced into a 2-0 lead when Gabriel Jesus was found free in the box to head in a second goal, before an incident between Granit Xhaka and Trent Alexander-Arnold livened up the Anfield crowd.
Then Liverpool were given a lifeline when Salah found some space at the back post and tapped home from Jordan Henderson's effort, though the Egyptian could not get his second from the penalty spot - despite Klopp's initial reaction.
