It is quite easy for Lyon to return to the top 10 because the points difference with the clubs above is very close, but still Lyon's position is very unsafe because Lorient and Toulouse also have a very close gap to Lyon.
On this occasion, I am sure that Lyon will soon improve and we will see that at the weekend Lyon will face Le Havre and if Lyon is successful they can beat Le Havre. I am sure that Lyon will start to improve.
If Lyon is able to win at home to Le Havre this weekend, then the number of points for both will be the same even though Lyon will not immediately take Le Havre's position in the Ligue1 standings. I see that from the top ten to fifteen in Ligue 1 this season, the competition for points is starting to look fierce, so this will not make it easier for Lyon to protect themselves from being chased by other teams who are also trying hard to get out of the relegation zone.
