Raheem Sterling was furious that both the referee and VAR turned down a Manchester City penalty following Kurt Zouma's challenge on the England forward.
Chelsea put the brakes on City's crowning as Premier League champions with a 2-1 comeback victory, with goals from Hakim Ziyech and Marcos Alonso cancelling out Sterling's opener.
At 1-1 in the second half, Sterling was driving into the box and appeared to be brought down under a clumsy tackle from a retreating Zouma.
Referee Anthony Taylor waved play on, and a VAR check confirmed his no-penalty decision, to Sterling's bemusement and the 26-year-old vented his frustration after the match.
