Chelsea boss Roberto Di Matteo admitted he was disappointed not to have taken something off Manchester City.
The Blues had looked on course for a big victory at the Etihad after Gary Cahill's deflected goal put them ahead on the hour.
But a Sergio Aguero penalty followed by a cool finish from Samir Nasri meant Chelsea left empty handed.
"I think it was tough on us, we fought hard and I think we deserved a point at least," Di Matteo told Sky Sports.
City's equaliser came through Aguero's penalty in the 78th minute after Michael Essien had been penalised for a handball.
And Di Matteo felt the spot-kick was crucial.
"It gave them a big lift, we were defending very well at that point and I think that just gave them that little hope they needed," he said.
"We defended well to that point - it was a bit harsh, it was handball but he could not disappear and he was very close to the ball. It was harsh but it was handball."
The visitors lost Branislav Ivanovic to injury in the first half.
"He's complained about a tight muscle and we'll have to see how that is," added Di Matteo.
Fernando Torres started the match and was later substituted but Di Matteo was pleased with his overall contribution.
"I thought it was terrific from him, but from the whole team too. We were just unfortunate we didn't get something," he said.
