Now it's the other way around—Real Madrid is playing like a farmer's league, while PSG is playing in a tough league. 
What are you saying, it happens sometimes that a big team will just flop completely, PSG has been there as well so what exactly is the point here for you and OP .. Besides, I don’t know of OP but I haven’t considered Ligue 1 to be farmers league infact there’s nothing like farmers league, it’s either the team has completely lost it or they have some bad players in the team.Ligue 1 is considered peasant because only PSG won. Lol
There is no stronger team than PSG in Ligue 1 league right? So many people consider this a peasant league, again only this team has big finances so it can buy any player it wants.
