The Serbian defender was given his marching orders shortly before Robin Van Persie's equalizing goal.

After a scoreless 45, Manchester United vs. Chelsea finally began to take off during the second half, which saw veteran striker Didier Drogba net his first Premier League goal since making a return this summer.

However, just as Blues fans thought they would depart Old Trafford with all three points, in the last moments of the match, defender Branislav Ivanovic was shown a second yellow and dismissed as the referee judged he had fouled Angel Di Maria.

And shortly after, Robin Van Persie fired home the goal the home crowd had been looking for, salvaging a point for the Red Devils and forcing the Blues to drop two.

Not surprisingly, Jose Mourinho was not impressed following the game.

"We have a little space now for our mistakes... or for referees' mistakes," he sniped to reporters.

"[But] if I say what is in my heart, I will get in trouble. I prefer not to talk about [the Ivanovic incident]. We had many things go against us, [and] the result was not very good but [it was] acceptable."

Mourinho reveals his thoughts on the game with some interesting post-match comments:
