French League 1 is not a very good league, to be honest. Of course, what I am comparing with are the Premier League, Serie A and La Liga. These leagues are behind in terms of competition. Like the Bundesliga, in League 1, the possibility of a single team becoming champion is mentioned at the beginning of each year. PSG is the most known of these teams. Success must come for them now in the UCL, almost everyone is sure that they will win League 1. Big surprises may occur, of course, we all know the Leverkusen example, but if such a situation does not occur, PSG will dominate the league for many years to come.
As long as conditions in Ligue1 remain the same as last season until they continue without stronger competition as happened in the Premier League, Serie A and La Liga. It will always be difficult for PSG to win the Champions League even though they have players who are used to competing in other leagues before making it to the PSG squad. And next season the PSG coach will use a different method so that the PSG team can get to the Champions League final next season while still being champions in Ligue 1 as usual.
