Petr Cech says an increase in aggression underpinned Arsenal's improved second-half showing against Liverpool on Monday night.
The goalkeeper made two superb saves during an opening 45 minutes in which the visitors created numerous chances.
Arsenal took control after the break and were only denied a first home win of the season by a combination of Simon Mignolet and the frame of the goal.
"It’s a goalless draw but I think it must have been an unbelievable game to watch for the neutrals"
"We made too many technical mistakes in the first half with loose passes and it gave them a few chances to counter-attack, but in the second half we improved on that," Cech told Arsenal Player.
"We were much more aggressive, we played much more in their half and obviously we created more chances, so in the end we could’ve won the game.
"In this game it’s very difficult to believe that it ended up 0-0. They had a few chances and most of the second half we were in control and had a lot of chances. We couldn’t find the winning goal.
"It’s a goalless draw but I think it must have been an unbelievable game to watch for the neutrals."
Cech was pleased to keep his first Premier League clean sheet for the club.
"I’m here to help," he added. "The first game didn’t go the way that I wanted but I always try to prepare and do my best.
"I’m very happy that I helped my team-mates, which helped me overcome my difficult moments, and it gave us a chance to search for the winning goal in the second half.
"Obviously we scored one goal which was disallowed, which is a pity but overall we can take a lot of positives form the game. We need to move on."
