St Etienne manager Christophe Galtier believes his side still need to improve across the board if they are to challenge for both the Ligue 1 title and secure their place in Europe.
ASSE stayed fourth in the overall standings following their 1-0 derby loss against 10-man Lyon at the weekend and will travel to Bordeaux for their next league match on Thursday.
Galtier is keen to recover immediately from the defeat which marked the end of his team's 10-game unbeaten league run.
"I found a lot of technical errors that make me think there was nervousness (against Lyon)," Galtier told L'Equipe.
"I just see that we still have a lot to do. We need to progress in all areas to compete with teams that have played in Europe for decades."
Bordeaux approach the game level on points with St Etienne and will be looking to improve on two successive draws against Reims and Sochaux.
Lyon play Nancy on Wednesday and defender Mouhamadou Dabo hopes his side will consolidate their position at the top of the table.
OL are five points clear of second-placed Paris St Germain and could move further ahead against bottom side Nancy, who have only one league win to show for their efforts so far this campaign.
"We took major confidence (in the game against St Etienne)," Dabo said.
"The win must continue our momentum with a very important week ahead of us.
"Three points is good but it will be validated against Nancy."
Third-bottom Evian host fellow strugglers Troyes in a match which could go some way to easing their relegation fears should they win, after they suffered a 4-0 defeat by PSG at the weekend.
Troyes, who are one place above bottom side Nancy, picked up a valuable point in their 1-1 draw against Nice.
Elsewhere, PSG travel to fifth-placed Valenciennes in their bid to overhaul leaders Lyon.
Manager Carlo Ancelotti knows his team need to be 100 per cent focused on beating Valenciennes despite Sunday's top-of-the-table clash against Lyon looming large on the horizon.
"The team is ready for these two confrontations," Ancelotti told the club's official website.
"We showed a great reaction after our setback in Nice by chaining two victories at home against Porto (2-1) and Evian (4-0). The signs are positive at the moment.
"Valenciennes are very competitive, very dangerous at home, and are a side that does not score a lot of goals.
"We need to be focused 100 per cent on the game and not think about the game against Lyon this weekend."
Defending Ligue 1 champions Montpellier, who are currently down in 12th position, will be looking to pick up much-needed points away at Brest, while Ajaccio host Reims, Lorient play Sochaux and Bastia host Marseille.
In the other games, Nice host Rennes while Toulouse make the trip to the Grand Stade Lille Metropole to play Lille, also on Tuesday night.
