Benched for yesterday's 3-3 draw at West Brom, Kepa Arrizabalaga appeared to criticise his replacement Willy Caballero in the first-half.
The Blues dropped their record signing for veteran goalie Caballero for Saturday's trip to the Hawthorns.
Things did not go according to plan for Chelsea when they conceded a goal after just FOUR minutes.
And Caballero was slow to react as he dived in vain and the ball sailed past his left into the back of the net.
But it was Kepa's reaction on the bench which caught the eye of many viewers.
He could be seen remonstrating with midfielder Jorginho, appearing to criticise Caballero's decision to dive for the ball.
The Baggies jumped to a 3-0 lead at halftime, but Chelsea stormed back to draw 3-3 at the final whistle.
