Cech is happy with his teammates after they put in what he described as a "top level" performance.
"It was a very good result and we played a very good game," Cech told the press. "We were efficient. We had complete control of the game in the first half and most of the second half. We were a little bit under pressure after losing the first game at home but this was a good result for us.
"Every individual performance was at a really top level and as a team we were organised. Tactically there was no problem – we did exactly what we wanted to do. We created lots of chances and we converted them – that was the important part of the performance.
"The main thing [when colliding with the post] was to get to the chip and push it over. I just needed a little bit of time to get my breath back and after that I was OK."
Chelsea travel to Norwich City on Sunday.
