The Blues became the first side to keep a clean-sheet at the Camp Nou this season as they played out a 0-0 draw in the first-leg of their UEFA Champions League semi-final.
Forwards Lionel Messi, Thierry Henry and Samuel Eto'o had scored 90 goals between them in all competitions this season but Chelsea's terrific defensive discipline kept them at bay.
Cech made fantastic saves from Henry, Daniel Alves, Alexander Hleb, and Eto'o to give Guus Hiddink's men a great chance to reach their second successive Champions League final.
Cech, though, was quick to highlight the display of stand-in left-back Jose Bosingwa, who had to mark Messi.
"I think the biggest compliment should go to Jose because I think it was the second time in his life that he played at lef-back and it was against Messi," he said.
"But you couldn't see Messi on the pitch today. John Terry was also fantastic and I have to say so were all the other guys because it is not easy to come here and deal with all their attacking threat.
"But John was the leader of the back four and was brilliant. It is the first time we have got a clean sheet here but it is also the first time we haven't scored.
"The tie is still open but I think we can reproduce the same defensive work at home and we can always score goals at Stamford Bridge.
"Of course they have the best attack in the world, so it still stays 50-50.
"We just had to stay organised and everyone had to put in great effort for the individual and tactical work.
"As a team we had a great effort and we were rewarded with a clean sheet. But it was a pity that we had two good chances that could have been a goal. The goal would have been better but 0-0 is still a positive result.
"We wanted to stop them playing and then put them under pressure with our possession, which in the first half we didn't really do."
