Cech denied Thierry Henry, Daniel Alves, Samuel Etoâ€™o and substitute Alexander Hleb as the Spanish giants attempted to secure a precious advantage.
"They have a big attacking threat and we wanted to eliminate it," said Cech. "To keep a clean sheet at Barcelona is always a good result. Hopefully, we can repeat the same defensive performance at Stamford Bridge â€” plus at home we always score."
Blues skipper John Terry said: "There is nothing better than keeping one of the best sides in the world at bay. We have a chance now to get into their faces and not give them the opportunity to play."
