Lyon is back in good form so that bet on them will be safe choice, I have Lyon on my bet slip and I think they can handle against Metz so nice, Lyon is much strong and it looking they will win this match against Metz today, so Lyon ML is very safe from my point of view.
Personnaly, I will never bet on OL because they are one of the most unstable teams in Ligue 1. Able to win 6-0 versus Nantes but also to lose 4-2 versus Dijon and 1-0 versus Lorient.
