Lyon manager Remi Garde is looking for a ``significantly improved'' mindset from his side against Sochaux tomorrow following their humbling defeat at Bastia two weeks ago.
Les Gones have seen their Ligue 1 title hopes fade in recent weeks although their 4-1 loss Frederic Hantz's side last time out was still regarded as a big shock.
The setback was the third match in a row Lyon have failed to win and they are now consequently eight points behind league leaders Paris St Germain.
Garde welcomed the international break as it has given the side a chance to regroup.
``We needed to put a number of things right. It had to be done even with some players on international duty,'' he told the club's official website.
``It worked well. This has been quite positive.
``I tried to understand what had happened. I talked with a lot of individual players. I called for an awareness of individual responsibility in the collective service.''
On whether he could explain their defeat at Bastia, Garde added: ``I have some answers without certainty about everything.
``A lack of humility? I maintain that elite sport is a school of humility. We must learn to question constantly.''
Lyon are boosted by the fact they have a near fully fit squad, with Serbia defender Milan Bisevac the only absentee due to suspension.
However, Garde knows his side cannot afford to underestimate the challenge of Sochaux, who occupy the final relegation spot but are capable of upsetting the odds - as they showed in a 3-2 win against PSG last month.
``I think Sunday's game is extremely important. It is very important for the future. Our mindset, our involvement should be significantly improved,'' Garde said.
Sochaux are also going through a lean run and are without a win since surprising the big-spending Parisians.
Boss Eric Hely is desperate to avoid stretching that run to six matches although he is aware Lyon will pose a significant test.
``OL has several players capable of making a difference,'' he told the OL Tribune.
Lisandro Lopez is the player that has impressed the 48-year-old, who added: ``I have twice faced OL as a coach and the player who impressed me the most, in his travels and his intelligence game is Lisandro.
``Lisandro is football. This is exactly the style of player that I like.''
