Yet again the Chelsea legend makes the list - this time for his outrage at physio Eva Carneiro's decision to run onto the pitch to treat Eden Hazard without his permission during a 2-2 draw with Swansea in August 2015. The Blues manager was visibly irate and screamed 'son of a bitch' in Carneiro's direction after what he portrayed as a complete lack of 'understanding of the game' by the physio, which left his side temporarily with nine men on the pitch following Thibaut Courtois' earlier sending off. The incident was enough to sour Carneiro's relationship with the club and she was banished from the bench in the games which followed, before she eventually left the club and took legal proceedings against her employers.
