The Ligue 1 club's trainer, Rene Girard, also believes that three points are essential to have any hope of finishing above Arsenal and Schalke in Group BOlympiakos head coach Leonardo Jardim has insisted that home support can help his team beat Montpellier in an “important” clash on Tuesday night.
The Greek side scored a late goal in the match on French soil to win 2-1 a fortnight ago, which gave the club their first victory of the Champions League group stage.
Jardim hopes when the two teams meet again - this time at the Karaiskakis Stadium - that their individual quality combined with the spirit of their supporters will see them collect another three points.
“It is an important match,” the coach told reporters. “If we win we are likely to secure qualification for the Europa League, which is one of our objectives, and we will also edge closer to our primary goal: to finish second in the group.
“Montpellier are a very difficult opponent, which they showed in France. We should not forget that they are French champions and are a very strong side with very good players.
“However, Olympiakos are also a very strong side with individual talent, and I believe that with the help of our supporters we will secure three more points.”
Rene Girard - the coach who guided Montpellier to the Ligue 1 title last season - also branded the game as important, and admitted that fellow Group B competitors Arsenal and Schalke have an advantage.
“I don't know if tomorrow's match is make or break, but we have to do what needs to be done. Olympiakos are very experienced in the Champions League,” he said to gathered media on Monday.
“Arsenal and Schalke have the advantage. It's like we're playing in a mini league with Olympiakos as our main rival.
“We have shown that we can take on any side, whether that is Arsenal, Olympiacos or Schalke. The French league is our priority, but that doesn't mean we don't want to do well and learn from our experience in the Champions League.
“We will play our own game, be serious and look to avoid the mistakes we have made in our other Champions League games.
“It's an extremely important match and we can only have a hope of winning if we are serious. Playing with two forwards does give us an extra edge compared to playing with just one, but every player must do his duty.”
