Lyon head coach Hubert Fournier reveals he will hold talks with the club's board during the winter break to decide the best way forward after a disappointing few months.
OL last won a Ligue 1 fixture back in the beginning of November and have taken just one point from their last six league matches.
The only positive results the club has picked up of late was a win over Valencia in the Champions League and qualifying for the quarter-finals of Coupe de la Ligue.
They have dropped down to ninth in the league table after their 2-1 loss to Ajaccio on Sunday and Fournier admitted he was very concerned about the situation the club is faced with.
"The team has been very weak defensively and sterile in attack since we have gone on this losing run and doubts started creeping in," he told the Ligue 1 website.
"We decided to change things tactically from the Coupe de la Ligue match against Tours. We started the match very badly. The players were trying but they were too clumsy. We tried to correct things after the break and it was better but not enough to get an equaliser. It is a new disappointment and we need to do better.
"We finish 2015 with a group of players who are exhausted after a trying first half of the season. I am not going to hide behind it but it is true that we have played nine matches without certain players and we have felt it.
"Mathematically we have picked up one point from the last 18 available, so it is difficult to do worse. December has been particularly disastrous despite the victory at Valencia and our qualification for the quarter-finals of the Coupe de la Ligue.
"We will meet with the board during the winter break and we will see. We will need to work out what is in the best interests of the players and the club. OL's situation is much more worrying than mine," he concluded.
