What happens is that for this to happen many things have to happen, among them that PSG remains as part of the UCL, which they can do, and this will motivate investors to leave Ligue 1, but the level must be more competitive, they cannot continue to show in Ligue 1 a football that is not so good, at least in the Europa League I liked how Lyon did, but they only show that level in high competitions, in Ligue 1 the other teams must do better.
If the conditions happen like this every season then maybe investors will have difficulty entering because they prefer other Leagues compared to Ligue 1. There needs to be some kind of change that must be made especially for each club that is there because now this league is seen as less competitive. If PSG can reach the best level in the Champions League then I think that is reasonable because they do have quite good financial resources.
What is needed now is how other teams can reach a much better level like Lyon when competing in the Europa League but they failed again after not achieving victory when facing Manchester United in the second leg. Next season there must be an effort that needs to be made by each team and it must really happen because it requires big changes.
