Supporters were left bewildered after Liverpool midfielder Wataru Endo avoided a red card for a challenge on Brentford's Christian Norgaard.
Endo made the challenge during Liverpool's 3-0 win at Anfield but avoided a yellow card following a VAR check.
The Liverpool player lunged in and caught Norgaard on the shin with his studs. The decision over the punishment was a difficult one to make given that both players were lunging in for the ball.
However, it was somewhat surprising that Endo didn't get booked.
Many onlookers were adamant that the 30-year-old should have been dismissed for his actions.
