Cristiano Ronaldo has regularly been praised for his professionalism, especially since returning to Manchester United, but the forward's strop during the win at Brentford demonstrated he can sometimes let the mask slip.
The veteran was spotted throwing a strop on the bench after being substituted during the 3-1 victory, his first game back after missing the draw at Aston Villa through injury.
Ralf Rangnick's team still won the game, with their third goal coming from substitute Marcus Rashford after Ronaldo's withdrawal.
