Barcelona leads the Champions League Group B authoritatively. The Catalan Club has taken maximum points from matches played so far and will try to continue this series and beyond the game in Greece.

On the other hand, Olympiakos has not managed to win yet another point in the group. The Greek club is going through a rather bad period. The elimination from the Champions League is a certainty and the chances of getting at least one qualification in the Europa League drop with each match played. In the domestic competition, the Piraeus team is only in fourth place this season.
