Montpellier coach Rene Girard believes Evian's desperation will make them a dangerous opponent when the sides meet on Saturday night.
Evian are languishing near the foot of the Ligue 1 table in 18th place, and are without a win in eight games.
Montpellier, meanwhile, sit in eighth place and remain firmly in contention for European qualification next season.
But, Girard knows his side could easily come unstuck on the road if their mentality is not spot on.
He told a press conference: ``We know that it will be complicated, they are a little bit in trouble now, so we will have to work very hard.
``But we have to maintain our recent form, we have been moving up the league.
``We are challenging for a European place but I do not think it is something we can target just yet, even though mathematically it is possible.''
Evian boss Pacal Dupraz, meanwhile, has told the club's fans to keep the faith and get behind their side tomorrow night.
``Until it is proven otherwise, we are not condemned,'' he told a press conference.
``After 19 months of presence in Ligue 1, I think we do not need to be ashamed that we are in trouble.
``I am happy in the knowledge that the responsibility will be mine if we fail, but I do not want to hear too much about us failing.
``We have to focus on ourselves, because our way out of this situation has to come from within the club and we need everyone behind us.''
