Prior to the game ending in a mass brawl, Oleksandr Zinchenko and Jack Grealish enjoyed a leisurely warm-up playing keepy-uppy with each other over 50 yards apart.
Manchester City emerged from the game in Madrid victorious on aggregate over the two legs with the second leg being marred by ugly scenes at the end of the game.
Kevin De Bruyne's first leg goal proved the difference as City advanced beyond a committed, if at times overly aggressive, Atletico Madrid side.
Two substitutes on the night, Zinchenko and Grealish, have brought delight to social media after a video taken from the stands shows them skilfully booting the ball to one another from opposite ends of the same half at the Wanda Metropolitano.
The video, captioned 'Zinchenko and Grealish making it look way too easy in the warm-up today', shows the Ukrainian player doing keepy-uppies by himself at the by-line before launching the ball to Grealish on the half way line.
Grealish, who drew the ire of Stefan Savic at the end of the second leg before it carried on into the tunnel, then cooly controls the ball with his chest before letting it fall to his right foot.
The moment of the video then comes when Zinchenko produces a majestic touch with his weaker foot before controlling the ball again and passing it back to Grealish.
The sequence continues for short while before Zinchenko, who impressed people on social media with his deft touch, makes a mistake at the chain is unfortunately broken.
No doubt the two superstars did not have any trouble restarting their incredible game.
Meanwhile, Pep Guardiola has admitted that Manchester City find themselves in 'big trouble' after sustaining a number of injuries coming through their tie in Madrid.
The Spaniard told BT Sport: 'We are in big trouble, so we can't forget we played three days ago, travelled, come here, have a lot of injuries now and I don't know what will happen in the next weeks but today we celebrate because it is the third time in Manchester City's history we are in the Champions League semi-finals.
'We cannot play all the time and score four or five goals, we are human beings - we come from a difficult game against Liverpool.'
Both De Bruyne and Kyle Walker were forced off in the second half as Atletico chased the game and piled the pressure onto Guardiola's side.
They came it through displaying the sort of coolness earlier exhibited by Zinchenko and Grealish in the warm-up and as a result will face Real Madrid for a place in next month's Paris final.
