Even if Lyon's level of play is like in the UEL, I'm sure PSG will play the same role and play the same level of play as in the UCL, so it's clear that PSG is superior in terms of strength and Lyon will not find it easy to beat PSG with a lower level, especially when facing Man United, basically this club is in poor form so it can't be compared to facing PSG who are in good form both in League 1 and in the UCL.
For some reason these teams are more popular in the biggest competitions, in Ligue 1 it is known that PSG is the best, for me PSG has no rival in Ligue 1, so they can win Ligue 1 quite relaxed, the only way is for them to make a difference similar to what they did or what happened in the Bundesliga, when Leverkusen surprised them with Xabi's winger, a Xabi would have to arrive at Lille, Marseille or Lyon, I think that is the only way they can change Ligue 1.
