PSG spent big, it was strong enough to win everything, but it wasn't "shaped" by good competition.
I agree with you that the tougher the competition in the domestic league, the more motivated a club will be to improve. I'll take the example of the Premier League for example, they get tough competition from all clubs, we can't easily predict matches there, because there clubs that are considered weak can become a stumbling block for big clubs. And we can see what they can do in European competitions as a result of the intense competition in their local competitions. Unlike Ligue 1, we can see what they can do in European competitions, especially the Champions League. They can't say much there.
We can't deny things like this, because after all this is part of the mental formation that will be very useful.
Yup. Even in real life, study or work. If you're the best at your class or at your office by far, you get lazy. Why work hard when working less hard is easier?
Football is perfect example. PSG play so lazy, same as Bayern at some point. But Manchester City themselves Pep said they got so good in 5/6 years mainly because Liverpool pushed them so hard. No better motivation than to be better than others who are SO good
It made me think of an example like this forum too, you have shit campaigns where managers don't care about quality of posts, if you don't want to make effort and compete for better pay, those are good for you.
