The Blues won their first ever Champions League trophy last season although they only managed victory in one of their seven matches on the road.
The Londoners take on Danish outfit Nordsjaelland in Copenhagen on Tuesday night, with the Czech Republic number one looking for a win in their first European away match of the campaign.
"In the knockout stages, we shrugged it off," he said. "That was the important part of our winning campaign.
"In the group stages, it wasn't the case. But things changed in the knockout stage. Even the results away from home changed. We'd like to continue from there and start with three points. But there's no obvious reason why it happened.
"You want to win every game, home and away. At the start of every campaign, it's important to get as many points as possible from the start so you qualify early. That's the ideal situation. We want to get the points early."
Chelsea drew 2-2 with Juventus in their first match of the competition.
