Lyon's rise in the standings is really difficult to overlook. If you ask me which one deserves that spot more I would say Lyon now. Because they reached this point from the relegation zone. This is a huge improvement. Such comeback is a very challenging work you know especially when your players have a really bad morale.
Lyon is also not an easy opponent for Lille because they have played very well recently, Lille also don't want to share points let alone lose points against Lyon because they have to secure their position in 4th place where of course to secure a UCL ticket next season, they have to can win the match against Lyon later in front of all their supporters playing at Lille's home ground, of course this is their opportunity to get full points against Lyon, even though they will certainly experience difficulties and obstacles to be able to win, they will definitely play as hard as possible.
