Lyon coach Remi Garde has warned his side against complacency after they surged up to seventh place in Ligue 1 following last weekend's dramatic derby victory at St Etienne.
Jimmy Briand's injury time winner gave Garde's men their second straight win and moved them closer to Champions League contention after their dismal start to the season.
But despite starting as big favourites at home to struggling Valenciennes on Saturday, Garde is aware all his side's recent good work will mean nothing if they have not come back down to earth.
Garde said: ``We mustn't rest on our laurels. The derby result gave us a lot of joy and hope, but only three points.
``The championship is very tight and we have to continue with our new-found confidence.
``It will be very tough against Valenciennes on Saturday. The players set a benchmark in the last two matches. I think they saw what the situation was and responded as a team.''
Lyon are definitely without defender Mouhamadou Diabo with a cartilage injury while midfielder Jordan Ferri faces a late fitness test. Remy Vercoutre will replace Mathieu Gorgelin in goal.
Having showed glimpses of good form in their 3-1 win at Ajaccio two weeks ago, Valenciennes' hopes of a second straight win were shattered by an injury-time equaliser by Benjamin Strambouli for Montpellier last week.
The result left the club in the drop zone and despite hints of an upturn in fortunes under new coach Ariel Jacobs, he is only too aware of the challenge facing his side against Garde's in-form men.
``Lyon's last win in the derby at St Etienne did them a lot of good and gives them a breath of fresh air and a boost of confidence,'' said Jacobs.
``One must be aware of the quality of this team. This is not another match for us like Ajaccio or Rennes. This match will be quite different.''
