I can't say that league title is actually worthless. But when it is PSG and they are only being able to win the league titles, I will say that it is genuinely worthless. Because they have the most amount of money compared to any other club in the league.
So they are supposed to win the league title. I know that they are not having the type of success that let's say Bayern Munich is happening. But that makes things worse. Because there are teams which have money in the Bundesliga. But Bayern Munich is so good that they are not facing too many problems. But PSG is not being able to do that. At least PSG is not winning the league title 10 years back to back.
In the English Premier league we say its competitive because one club cannot win the league for 10 years back to back. But in the French league we say PSG is not a good club that is why they cant win the league 10 straight years. Why cant we also say its a competitive league that's why PSG cant win it that way.
PSG has not lived up to expectation since the takeover, but we cant judge them solely by their failures in the champions league. How long did it take Manchester City, spearheaded by the best coach in the world to win a champions league?
The league can never be worthless, however you look at it.
