Valenciennes coach Daniel Sanchez feels his side are set for a pivotal moment in their Ligue 1 campaign at home to Brest tomorrow night.
Sanchez's men have not recorded a win since they beat Evian in Week 19, losing three out of their four games, which has left them in 12th place.
Brest head to Stade du Hainaut also out of form, on the back of three successive defeats.
Sanchez knows victory could kick-start his team's hopes of closing back up on the Europa League places, while defeat would leave them stuck in a mid-table rut.
``Saturday's match is really very important. It can allow us to go forward or back to heighten the doubt. This is a pivotal game,'' he said.
``A win against Brest would be a greater difference because they are a direct competitor and against these teams, it is important to get the difference in the end.''
Forward Anthony Le Tallec called on his side to get back into gear against Brest.
He added on the club's website: ``We are living a difficult moment because we have not won in 2013.
``We must click in this match against Brest.
``Earlier in the season, we have shown that we can achieve great things and at home we need some reassurance.
``To regain the confidence you need to win, simple. We need a victory to settle everything. I hope it will arrive on Saturday.''
Brest are a few places further down in 15th, and coach Landry Chauvin is hoping for a response to their 2-0 defeat at Nice.
He said: ``We had wanted to show more teamwork and determination, but it was perhaps our worst performance of the season.
``We failed mentally, and if that happens you can't hope for better than what we got.
``But we knew that road to Ligue 1 survival wouldn't an easy one, so the only thing to do now is to shut up and get back to work.''
