The Blues entered the game in the knowledge that major title rivals Manchester City had already beaten Hull, making three points at Villa Park important in their bid to maintain top spot over the remainder of the season.
However they slipped to a surprise 1-0 loss, with Fabian Delph steering home an impressive goal after Willian has been dismissed for picking up a second yellow card.
After the eventual winner, the red mist descended with a wild challenge from Ramires on Karim El Ahmadi resulting in a red card for the Brazilian, while Mourinho was himself sent to he stands as tempers flared on the touchline.
‘The Special One’ was reserved in his comments towards referee Chris Foy after the final whistle, insisting that he did not want to get himself in any more trouble:
“It was a good, solid performance against a good team,” he told Sky Sports.
“Defensively, we were really strong and we had no problems coping with the danger that Aston Villa has.
“After that, I prefer not to comment because I don’t want to bring the game into disrepute and I don’t want to be accused.
“I prefer not to comment because if you want to speak about big decisions, you don’t just speak about the red cards.
“If I speak I’m in big trouble, and I don’t want to be in big trouble, and if I speak I’m accused of bringing the game into disrepute.
“The referees do what they do, they do and they go home, they do and they don’t go to the press, they refuse even to exchange a couple of words when one person, like me who has been in football for so long, asks politely, ‘Can you speak with me for five seconds?’ and it’s ‘No, I don’t speak with you for five seconds’.”
