Manager Avram Gant was content with Chelsea's performance in their goalless draw away to Schalke in Champions League Group B.
The Blues were far from their best in Gelsenkirchen and were twice rescued by the woodwork, but remain on course for a place in the knockout stages of the competition.
Grant said after the game: "We wanted to win but it was not easy to play Schalke at home.
"They needed to win because a draw was not good enough. It was not a bad result but not our best game.
"After so many good games in a short time we can have one game that is not in the high level. It is also an away game against a team who feel very good playing at home.
"The Champions League is not the league it is another competition. You need to fight for the result and it is not easy to play away from home.
"We are in first place and everything is in our hands and I am very happy and confident about that. But we need to continue our job because it will not be easy.
"I don't think we defended so badly, it was not a bad game. It was not our best performance, but not a bad game for us."
Meanwhile, the Blues are waiting to learn the extent of a calf injury which forced goalkeeper Petr Cech out of the game in Germany at half-time.
