Tottenham Hotspur manager Jose Mourinho has torn into referee Andre Marriner following Thursday night's 1-0 loss at home to Chelsea.
Spurs once again seemed to struggle in the absence of talisman Harry Kane, with the Blues picking a vital win thanks to a first-half Jorginho penalty.
It was the decision to award the Blues the spot-kick after Eric Dier brought down Timo Werner inside the box that angered the Portuguese, and he couldn't hide his frustrations after the match.
"I didn't like his performance. I have a good relationship with him and that gives me a good position to tell him I don't like his performance," he said.
He however admitted they were far from best during the match, particularly in the first half when Chelsea largely dominated.
"It was a bit of a struggle but how many chances did they have? We didn't have the ball, correct, we didn't create in the first half, correct," the Portuguese told BT Sport.
"But the struggle was the penalty. In the end, a penalty decides the game. In the end, they score a penalty which is not a penalty that you say is a dangerous situation, one on one, almost scoring. It's a penalty that is difficult to accept and to lose the game like this is a bit painful,"
"But in the second half we were different and Lucas [Moura] and [Erik] Lamela helped to change the dynamic. The feeling I have is that we kept together until the end. To finish with a positive spirit helps.
This was the first time Mourinho was tasting back-to-back home defeats in his managerial career, following the 3-1 loss against Liverpool.
It was also their third consecutive defeat, leaving them eighth on the table standings.
