The Gunners struggled to keep the ball out of their half in the first 45 minutes, but vastly improved their performance in the second half of the game against the Reds, and could have come away with a win if they were awarded some luck.
Cech believed the Gunners' improved performance in the second half was the source of encouragement for Arsene Wenger's men. He said: "Well I would say the positive thing out of this game was the number chances we created in the second half because we made plenty of mistakes in our positions first half and the game was played more in our half which we didn't want.
"In the second half we improved that and we played more in the Liverpool half and we created chances. This is something that is positive as we managed to get back into the game after the first half and the thing is to be more efficient and clinical in front of goal to find the winning goal which we could not find today."
"I think today was a particular situations both central defenders couldn't play," he added.
"Obviously Laurent and Per couldn't be here and it was a big game so when you jump in there was a bit of pressure on Gabriel and Calum. Although Calum made a few bad passes in the first half he kept his head up and they tried to do their best and obviously when you play with a back four that I used to play with that is a bit more experienced and then you need to communicate more to make sure everybody is in the right place in the right time because with the experience the players will get in time they will improve that. I believe that today the lads that came in did what they could to play well."
