The clip is from the first leg tie Barcelona won 3-0 rather than the humiliating 4-0 defeat they suffered in the second leg.
Messi had been accused of time wasting throughout the game and referee Bjorn Kuipers tells him: "Messi, come on, show some respect.
"Every time you do it!"
Six-time Ballon d'Or winner Messi turned in a vintage performance that evening, scoring twice with his second goal coming in the form of a delightful free-kick.
:video_camera: UEFA will premiere a documentary on 11/16 called "Man in the Middle". Included is a conversation between Bjorn Kuipers and Messi during Barça-Liverpool where Kuipers tells Messi: "Let's go! Hurry up, show me respect. You do it all the time (time wasting). Let's go!"

But the real story was Liverpool's second leg comeback and Messi didn't have as much success at Anfield.
He was almost immediately put in his place by Andy Robertson, who ruffled the 33-year-old's hair while down on the ground.
Despite the love many Liverpool fans have for the clip, Robertson himself doesn't look back on the incident fondly.
"When I look back on things I don't really regret anything because I feel as if everything is experience that makes you what you are," the 26-year-old explained to Daily Mail.
"But I do look back on that moment with Messi as one regret. I don't like seeing it. When I saw it afterwards I was gutted.
"We all had the attitude that day that nothing was standing in our way to get to that final and we created that atmosphere around the stadium and me and Fabinho were tracking him and there was a tangle of legs and we were on the floor. To do that to the greatest player that has ever played..."
The former Hull City man goes on to explain he wanted to win at all cost during the highly emotional contest back in May 2019.
"I have nothing but respect for him and Barcelona, but we went into that game with the attitude that we were 3-0 down, we needed a miracle, we needed something special and if that little thing stopped the best player in the world playing to his highest potential."
Liverpool did indeed win the tie 4-3 on aggregate then go on to win the Champions League that season, defeating Tottenham Hotspur in the final.
