Cech was recently interviewed by former Chelsea teammate Terry and talked about the possibility of Arsenal breaking Chelsea's record of only conceding 15 goals in the league in a single season.
Cech said: "Well, you know, I have to say that Arsenal are doing really well now. The season has just started, but there has to be a starting point."
"If they can continue like this, then they have a chance to break Chelsea's record for the fewest goals conceded in a Premier League season, but at the same time, it is not easy. 38 games, sometimes you need a little luck. I think it will be difficult for them to break our record, but I will continue to pay attention because they have really started well."
Talking about helping Chelsea set this record, Cech said: "I must say that I am proud of it, because you need to maintain stability and the whole team needs to work together. In fact, only conceding 15 goals in the entire Premier League season is quite an incredible feat."
"You need everyone's contribution, of course, if you have people who can work together between the offensive and defensive phases. "We had Makelele and everyone saw and thought, 'Every time you need him, he's there.' Of course, you need creative players to score more goals, but if you have a solid structure and everyone really works together and defends well, then in the end that will win you games."
Arteta's style of coaching Arsenal. Cech said: "On the other hand, it's nice to see a team that is also proud of its defensive record because now everyone is talking about organizing attacks from the back, creating chances and scoring goals."
"But at the end of the day, if you don't concede goals, you only need one goal to win the game, and that's what Arsenal have been doing so far, so let's see how they continue to do it."
