Chelsea boss Avram Grant has said that nobody will be underestimating Greek side Olympiakos. This is the first time in nine years that the Greeks have reached the knock out stage of the Champions League.

"Make no mistake, not one player or a single member of staff thinks this will be an easy game," the Israeli told a news conference on Monday.

"We have a lot of respect for Olympiakos. They haven't lost in six games and have showed in Europe they can compete with the best teams."

Olympiakos boss Takis Lemonis admitted the side will go for goals: "We can't talk about qualification if we don't score a goal.

"Our motivation is to break the tradition which has seen Olympiakos always fail to qualify against English teams.

"There is pressure and anxiety but that is a good thing. Olympiakos's target in any game is to play to win."
