Brendan Rodgers lamented the inconsistency in Premier League officiating after seeing Scott McTominay avoid a red card for a lunge of James Maddison.
The Manchester United midfielder escaped with a booking as he stretched to win the ball after a heavy touch early in the second half of the 1-1 draw with Leicester City.
The Foxes players were furious at the decision but it wasn't reviewed by the VAR and McTominay stayed on the pitch and was substituted soon after.
