The popularity of Ligue 1 is going to decrease a lot since Mbappé has left PSG. He was probably the only one who was keeping the PSG club relevant towards the whole world. And now that he has left, the world is going to stop following PSG. The majority of the people that actually follow Ligue 1 do it because of PSG. So when the popularity of PSG is going to decreases, the popularity of Ligue 1 is going to decrease automatically. By now people also probably have understood that PSG is not actually a very competitive team. They just have a lot of money and does not have any competition in the domestic league. That’s why they have been able to win the Ligue 1 title again and again. They have never been able to win the Champions League trophy and I do not see them breaking that record in the next season as well.
One of the factors in the popularity of League 1 in the past was because of the presence of PSG star players such as Lionel Messi, Neymar and also Kylian Mbappe, but the PSG star players left League 1 and moved to other leagues and the only star player who remained for a long time was Mbappe, but unfortunately this season This will be Mbappe's last season in League 1 and next season we won't see Mbappe at PSG or in League 1, so it's only natural that League 1's popularity will decline because their fans will definitely start watching Mbappe play in other leagues and no longer watch League 1. and we know how popular Mbappe is among PSG fans and the world's eyes.
PSG is not a competitive club. This club shows everyone that having star players is not enough to provide good performance in international competitions such as the Champions League and many players leave because PSG is unable to provide prestigious titles because the chances of winning them are very small, who knows what will happen? what happens to PSG next season is how they compete in the absence of star players. I'm not sure PSG can play well in the Champions League. Most likely PSG will be quickly eliminated before reaching the final.
