Chelsea suffered their first English Premier League home defeat under the reign of Portuguese manager Jose Mourinho as they fell to a 2-1 loss to bottom-placed Sunderland on Saturday. The loss saw the Blues boss go on a referee rant as the former Real Madrid manager was upset with a late penalty the referee gave to Sunderland, one which lead to the Black Cats' second and winning goal.

Mourinho wasn't the only one upset with that decision, though.

Chelsea's assistant coach Rui Faria lost his temper during the game after Mike Dean, the game's referee, awarded Sunderland a 82nd minute penalty which they converted to win the game. The Blues' assistant was seen protesting the decision before Mike Dean sent Faria to the stands. This is when Mourinho's second in command completely lost it as he started shouting at the referee causing for him to be restrained by Mourinho and other Chelsea staff members before it escalated.
