Antonio Conte was sent to the stands during Chelsea's clash with Swansea after angrily protesting a decision given against his side.
The manager was left fuming after officials failed to award a first-half corner to Chelsea when a ball appeared to come off Alfie Mawson before going behind.
And Conte took his frustrations out on Lee Mason as he shouted and gestured wildly in the face of the fourth official in dispute of the decision.
Conte was swiftly reprimanded by referee Neil Swarbrick and was sent to the stands for the remainder of the match at Stamford Bridge.
