PSG have the chance to erase some of the negative perceptions about Ligue 1 by winning the Champions League trophy. Ligue 1 reputation will increase, and they will become a team to be reckoned with in Europe.
Yes, unfortunately, they still think that PSG came from the farmer's league and will remain like that. In the end, it was PSG who could remove them all and fight until the final. Indeed, PSG has developed very well this season, but it is undeniable that several other top clubs from Ligue 1 have not been able to compete tightly against other top league clubs, and the league in Ligue 1 is very weak. Hopefully this will change over time like what happened in the Bundesliga.
Without meaning to belittle Ligue 1 but the positive reason why Ligue 1 is often called the Farmer's League is because only PSG dominates the league almost every season. PSG is one of the top European clubs on the same level as City, Madrid, Barca, Liverpool, Inter and other top teams. But I apologize to the other teams in Ligue 1 I think they still don't have the same level as teams like Arsenal, Chelsea, Bilbao, Dortmund, Roma or Fiorentina. I think you can understand what I mean. And because only PSG can be an elite team, it will be difficult if we expect Ligue 1 to be on par with La Liga, Serie A or EPL where each team has a level that is not much different.
For example, if you look at the statistics of each team in each league, PSG only has 2 defeats but other teams below them have 8 or 9 defeats. I even doubt PSG's defeat from Strasbourg because it seems like PSG is no longer playing seriously. But if we look at other leagues like EPL, Liverpool has 3 defeats and Arsenal has 4 defeats, other teams have 8 or 9 defeats. In Bundesliga Munich 2 defeats and Leverkusen 2 defeats. In La Liga the top 4 teams both got 5 defeats. Even in Serie A I think the teams in the top 10 are already at a level that is not much different. This shows that the level of competition in other leagues is more competitive and more interesting compared to Ligue 1 where only PSG is at the top level. There are almost no other teams that can be their competitors let alone beat them in the league.
