"At the start of every campaign it's important to get as many points as possible early on to qualify, then you can concentrate on the other games, that's the ideal situation," he told Chelsea's official website.
"We will treat the game exactly the same as our last games. Whether it's a final or not, you have to be ready if you want to win matches.
"This is the Champions League, we take every opponent seriously. We want to win, that's clear, we've done our homework, and we have an idea, but we want to put our own style on the game."
In the other Group E game on Tuesday, Juventus will host Shakhtar Donetsk.
