Antoine Griezmann receives his first Champions League red card for high foot on Roberto Firmino... after Atletico Madrid forward had scored twice to bring his side level against Liverpool
The 30-year-old had scored twice for Diego Simeone's men to bring them back on level terms after Liverpool's early blitz at the Wanda Metropolitano.
But after an excellent first half, the on-loan Barcelona man was given his marching orders for the first time in the Champions League by referee Daniel Siebert eight minutes into the second half.
The France international was trying to gain possession and lifted his foot into the air to try to do so, but only managed to catch the Brazilian flush in the face.
The German official's decision left Atletico boss Diego Simeone and team-mate Luis Suarez furious with Griezmann's dismissal, with the Spanish champions having to play the last 28 minutes with 10 men.
And his dismissal did end up costing the Spanish champions any points, with Mohamed Salah netting his second from the penalty spot as the Reds won 3-2 at the site of their 2019 Champions League final win.
Former Liverpool star Mark Lawrenson however told BBC 5 Live that the decision was harsh.
'It was coming past Griezmann and he's put his foot out and caught Roberto Firmino. My first thought was that it was accidental.
Yes, Firmino has been caught, but Griezmann was looking at the ball.'
Fans were also left split as to whether Griezmann's high foot merited being sent for an early shower.
One wrote: 'Griezmann was going for the ball, but it was reckless. Definitely a red card.'
But there were a fair few who were left fuming with the decision, with one Twitter user wrote: 'I've seen some horrific red card decisions in my time but that's not a straight red for Griezmann. Referee showing his Liverpool colours yet again.'
Another agreed, stating: 'In no universe is that a red card offence. Griezmann is going for the ball, the boot is high but it's incidental contact on Firmino.
'My goodness. Yet another refereeing blunder going against Atlético in the Champions League.'
One user however compared it to when Manchester United star Nani was sent off after connecting with Alvaro Arbeloa's ribs with a high boot at Old Trafford eight years ago, even though the Portuguese did not appear to see the Real Madrid full-back and had his eye on the ball.
The user wrote: 'How is that a red card for Griezmann.... That's like Nani red card vs Real in 2013... JOKE @ChampionsLeague'.
Strikes from Salah and Naby Keita had given Jurgen Klopp's men a two-goal advantage in the first 15 minutes of the Group B fixture.
But Griezmann pulled one back in the 20th minute after converting from close range following Koke's low drive from the edge of the box into the corner.
The France star then doubled his tally after a fine run from Joao Felix, again finding the corner on the slide to send the Wanda Metropolitano into bedlam.
