The Blues' hopes of coming away with a victory were dashed when Robin van Persie netted an equaliser with just seconds left on the clock, and Mourinho has had a lot to say about referee Phil Dowd's decision which ultimately led to the United goal.
Phil Dowd sent off defender Branislav Ivanovic in the 93rd minute which resulted in a free-kick from which United levelled matters to prevent the Blues from securing all three points, leaving Mourinho unimpressed.
"I prefer not to speak about the second yellow card, because if I have to speak about the second yellow I have to go through many things," he told Sky Sports.
"The penalty on Ivanovic, the accumulation of cards, the fouls that he was not giving, the throws-ins just in front of me."
After dropping two points on Sunday, Mourinho admitted he now has little room for error. "We have a little space now for our mistakes, or for referees' mistakes."
Despite the result, however, the Portuguese manager was still pleased with his side’s display.
"We were fantastic, especially in the second half. It was a
top-class performance, good control, we could score a couple more goals."
