Portuguese superstar Cristiano Ronaldo openly showed his disgust at his Real Madrid side's performance, away to Borussia Dortmund in the Champions League, as the Galacticos fell to a 2-0 defeat in Germany.
A Marco Reus double was enough to make it an uncomfortable night for the Spanish giants, who edged their way through to the semi-finals 3-2 on aggregate.
Ronaldo was left on the bench for the match after suffering a recent minor knee injury.
As the video shows, the mercurial player was not pleased at some of the things he was witnessing from the sidelines:
Paul Collins from the Mail Online also reported on Ronaldo's dissatisfaction on Tuesday night, commenting on his reaction when Dortmund scored the first goal of the second leg.
Collins wrote: "Ronaldo could be seen raging on the touchline, standing up with an expression of indignation after Reus rolled the ball past Iker Casillas."
With Madrid three goals ahead, it did not seem like a risk by Carlo Ancelotti in resting his star player, after the attacker has been troubled by minor injury in recent weeks.
Ronaldo has been the lifeblood behind Madrid's Champions League campaign this season, scoring 14 goals in his eight European matches this year, per Squawka.
It is the best goal return by any player in the competition's history, equalling Lionel Messi's record from 2011/12, per UEFA.com.
Ronaldo has been shown to have a short fuse in the past when things have not gone his way, but his outburst in the Westfalenstadion on Tuesday night can be viewed in two different ways.
It could be seen as a petulant outburst of a player who cannot handle watching his team-mates fail, as he sits helplessly on the sidelines, being forced to witness a club whose expectations are through the roof.
Does Ronaldo's outburst prove he cares?
But it can also be viewed that he really cares about his side and their progression through a competition they are synonymous with. In a world where footballers are accused of playing purely for financial gain, it is good to see one of the biggest superstars in the game wear his heart on his sleeve and display that he wants to win.
With Ronaldo back in their side for the semi-final, Madrid are one of the favourites to take the famous trophy that they have won on so many occasions and complete the Portuguese international's trophy collection as a Galactico.
