Cech felt they were back to their best in the 4-0 rout.
"The way we played, both individually and as a team, was very nice to see," Cech told chelseafc.com. "We truly deserved the 4-0 scoreline because we played really well, it was a great reaction after the first game and just what we needed. We went there to win, and we did, so we're very pleased.
"It was important to keep a clean sheet because you never know whether it will matter at the end of the group. Having lost the first game the group will obviously be tighter because we gave Basel a three-point advantage, but after the second round of matches everything is back to normal because they lost. A clean sheet is important for the confidence of everyone and of course for me as well."
