Gary Cahill led key figures at Chelsea in complaining about the refereeing in their draw with Swansea.
The Blues were held to a 2-2 draw in south Wales on Sunday, having taken the lead through Diego Costa.
Swansea fought back in the second half however, with a Gylfi Sigurdsson penalty drawing them level.
Within a minute, the hosts went 2-1 up after Leroy Fer raced through to fire past Thibaut Courtois – although replays showed he clearly fouled Cahill in the build-up.
Costa equalised late on at the Liberty Stadium, but Cahill in particular was incensed by the performance of Andre Marriner and his officiating team.
“It’s a clear foul,” he told the BBC. “I’m frustrated. Come on, seriously! You could be sat on the moon and see it is a clear foul.
“I took the touch away from [Fer], he came through the back of me. It was clear as day and seeing it back has made me even more angry.
“It’s all fun and games for the fans, isn’t it, but it’s the players who suffer. That kills me and my team. We have dropped two points which is massive in this league.
“Look at my face! It’s incredible. I said to the referee: ‘There’s three of you that can see that’. There were two fouls and between the officials they have said that they couldn’t see it. For me that is incredible.”
Cahill’s central-defensive partner, John Terry, posted the following image on Instagram, of Swansea defender Jordi Amat holding him in the penalty area. It has since been deleted.
Manager Antonio Conte was also displeased at the foul on Cahill, telling the BBC: “For the second goal, I think everyone can see the double foul on Cahill. I think there is a great mistake, a great mistake of the referee. But this can happen.”
In a later interview with Sky Sports, he labelled Marriner’s call as “a bad decision”.
