Fabian Delph's brilliant 82nd minute goal earned Aston Villa a surprise 1-0 home success to leave Premier League leaders Chelsea six points clear of Manchester City, who have three games in hand.
The loss was just part of the story for Chelsea who had two players and manager Jose Mourinho sent-off. Willian was dismissed for the Blues for a second yellow card and Ramires was dismissed in stoppage-time following a shocking challenge on Karim El Ahmadi and Mourinho was also sent to the stands by referee Chris Foy.
"Mourinho was very frustrated," said the Sunday Telegraph's Jason Burt
"Obviously the red card for Willian was quite soft and he was angered about that. They also had a goal disallowed and it was all conspiring against him.
"Then the incident with Ramires was right on the touchline near the managers and that just heightened the tension around there. You could see the game slipping away from them.
"The bigger question for me in terms of that game was just how poor were Chelsea going forward? Torres had a really bad match and it just heightened the lack of strikers in that team. The frustration boiled over.
"Then there is the other subplot, the conspiracy theory of Chris Foy sending off two more Chelsea players - six in eight games - so obviously people are getting upset about that.
"Jose Mourinho controlled himself reasonably well afterwards when he was speaking to the media but he made his points. He talked a little bit about Foy and said it was now a test of his character in terms of what he says about in his match report about Mourinho. Mourinho was adamant he did not abuse the referee."
View from the stands
Matt Lawton from the Daily Mail says that the pressure of the touchline can be too much for some managers and perhaps some of them should do what rugby managers and coaches do.
"He [Mourinho] did not really have a right to go on the pitch but in his defence Lambert was on the pitch as well. It is something that the LMA are looking into at the moment which is the whole technical area thing and maybe they should bring it back.
"There is this whole issue on manager's conduct on the touchline is a hot topic at the moment. Some managers do sit up in the stand - we all know that if you stand on the touchline it is much a harder to see the game because you are on the same level. If you watch rugby, they are always up so that they can watch the game. There is an argument for it."
