Chelsea boss Jose Mourinho fired a thinly-veiled criticism at the officials after his unbeaten home record in the Premier League was ended by Sunderland.
The Blues title bid was severely dented as Fabio Borini converted a late penalty after Cesar Azpilicueta tackled Jozy Altidore in the area.
There did appear to be contact between the players before referee Mike Dean pointed to the spot.
Mourinho, though, appeared frustrated by Dean's performance throughout, before also seemingly criticising referees' chief Mike Riley in a short and curt post-match interview with Sky Sports.
"I just want to say four things and I'm sorry because if you ask me more questions I'll repeat exactly the same thing," said Mourinho, who had not spoken at his previous three press conference following his fine for entering the pitch during a defeat at Aston Villa last month.
"Congratulations to my players because they gave what they have and what they don't have.
"Congratulations to Sunderland, because they won.
"Congratulations to Mike Dean because he made a fantastic performance and congratulations to Mike Riley, because what they did during the season was fantastic for the way the championship is going.
"Congratulations to all of them and I have nothing more to say."
Sunderland defender John O'Shea revealed boss Gus Poyet had used Mourinho's record as motivation for a win that significantly boosts their survival bid.
"Have a guess what the manager's team talk was?" he said.
"Be that team. Be that team to beat that record. Why not.
"What's the headline going to be in the morning? Mourinho loses his record.
"We're the team that caused it and the manager as always deserves a lot of credit."
Sunderland boss Gus Poyet feels survival is now within his side's grasp, following a week in which they also drew 2-2 at title-chasing Manchester City.
"I think with us, Sunderland, this year anything can happen," he said.
"It can go wither way. When no-one expects anything from us, we get a result from Manchester City and now we beat Chelsea here.
"In a good way, I think, because there was not too much difference between the two teams, apart from the shots from distance.
"Today we got the breaks that for some reason have been going against us."
