St Etienne manager Christophe Galtier wants his side to turn the frustration of their Coupe de la Ligue defeat in midweek to their advantage against Nantes on Saturday.
Galtier's side were unlucky to lose 2-1 to Ligue 1 leaders Paris St Germain with a goal from almost the last kick of extra-time.
But the St Etienne boss insists his team will bounce back against a side two points and two places ahead of them in the league table.
``It was a big disappointment to be eliminated, even if we knew that the task was very difficult,'' said Galtier.
``It was cruel to my players who gave much energy, determination and concentration.
``But we will re-engage the energies on Saturday and we will be determined to win against a direct competitor.''
Nantes, who were promoted to Ligue 1 last season, have their own incentive, however, as victory could see them break into the top four.
Currently they lie just one point and one place behind fourth-placed Bordeaux after a flying start to the season and are in good spirits after having progressed in the cup with a 1-0 win against Auxerre.
The statistics, however, are not encouraging for Nantes, who have not beaten St Etienne since 2000 when they recorded a 2-0 victory.
In the last 10 meetings between the teams, stretching back to 1993, Nantes have won on just two occasions.
Nantes manager Michel der Zakarian said: ``We must have the ambition to win.''
