It is not a farmer league and it is not the problem.
Even freaking Rennes that is a laughing stock in France for being the loser club has managed to beat Arsenal.
Not saying that Arsenal is a world beater but comparatively, they are way "stronger" than Rennes.
PSG gave away the game to a reserve team. No excuse about the league or anything. It all has to do with PSG weak mentality. The league is an answer for the weak. Other french clubs have done way better against better opposition with less good squad.
What the hell did I just read, dude? No offense.
Ligue 1 IS a Farmer's League by all accounts and all measurements. Compared to the elite leagues that is.
Mentioning Rennes is pretty pathetic considering the fact that they are the sole representative of Ligue 1 left in Europe as of early March. In December only QSG and Rennes were left. Is this supposed to speak highly of Ligue 1?
For all the elite leagues in Europe such a season would be absolutely shocking.
The problem is that all the players (most of them foreigners and not from Paris) are mercenaries with no love, dedication or attachment to your club. A club that they never dreamt about playing for as kids and never knew existed in the first place, most probably. Only money and false promises of instant success in CL (by buying yourself to success and employing and firing managers) keeps them there in the first place. That and never being allowed to leave (Verratti, Silva, Marquinhos, Rabiot etc.) and your club never having developed a winning mentality. Precisely partially due to the above mentioned reasons and others.
Ligue 1 clubs have won a grand total of 2 European trophies.
1 CL (clear case of corruption) by OM in 1993 and 1 Cup Winner's Cup by QSG in 1996 if I am not wrong. In 60+ years.
Both clubs having more money than most clubs in Europe back then as well yet only had those results to show for. Nobody has done better than QSG in Europe (of French clubs) either in the past 10 years. Not even close.
