Didier Drogba put Chelsea ahead from a header in the second half, before Robin Van Persie equalised during the injury time for Manchester United. John Terry feels that he and Ivanovic were headlocked at every corner and Chelsea had a couple of penalty appeals turned down by referee Phil Dowd.
Terry wrote: “It shows how well we are playing when you come away from Old Trafford disappointed with one point.
“Frustrated not to come away with three points. Thanks to all the travelling fans for your great support.
Chelsea boss Jose Mourinho also complained about Phil Dowd’s decision to send off Ivanovic and Chris Smalling foul on Ivanovic should have been given a penalty.
Jose Mourinho: “The red card, I was seeing it coming. If I have to speak about the second yellow I have to speak about lots of things.
“The penalty that Ivanovic should have been given (after wrestling with Smalling), the accumulation of yellow cards, the throw-ins. I know I speak always with my heart and get in trouble.
Chelsea remain unbeaten at the top of the table after the 1-1 draw. They host Queens Park Rangers at Stamford Bridge next weekend.
