Lyon coach Remi Garde expects a stern test on his side's visit to Bastia on Saturday, with the hosts fighting for Ligue 1 survival.
Garde's men lie in second place in the league, four behind leaders PSG with 10 matches remaining, and will be looking to keep the pressure on the capital club.
Bastia, meanwhile, are fighting just as hard at the other end of the table - sitting in 14th place but only three points off the relegation zone.
And Garde - whose side have won only three of their past eight Ligue 1 games - knows his men will have to scrap for the points at Stade Armand Cesari.
"I think Bastia have no margin for error," Garde said.
"The teams are different. Bastia is battling against relegation.
"For sure, the situation will be different than the first game (Lyon won 5-2 at home last November). Their mindset will be different.
"They are playing at home in a particular context.
"They are going to be hard to manoeuvre. We are going there to get the points we didn't get recently. We respect them but we are ambitious."
Garde hinted he may revamp his attacking set-up for the match, and his team's cause will be helped by the fact Bastia have conceded 52 league goals this term, the most in Ligue 1.
"We underline the lack of efficiency of our strikers at the moment, but that may be caused by the way we play and not only by the number of goals of our strikers," he said.
"For sure, I will have to try to find the best formation and the best tactics with the players I have for the team."
