Yes, PSG have been winning the French Ligue 1 over the past few years now, and that shows they are a strong team. That is why they always have the opportunity to keep winning Ligue 1. However, if I have to say the reason behind PSG dominating Ligue 1, it is because they don't have many competitors in the league. Other domestic leagues like the Premier League, La Liga, and Serie A have stronger competition.in the past few seasons, it’s not only PSG who have been doing well in the Champions League knockout stages Inter Milan have also performed well. In fact, Inter Milan reached the final recently, where they played against Manchester City. Despite PSG's efforts, all I have to say is that both teams have had a good record in the knockout stages recently.
Winning the Champions League is the ultimate for PSG. That is what will cement their place as an Elite team. PSG will definitely dominate their league every season, it will take a very bad season from them and an exceptional season from another team for them to take the league away from PSG.
When you look at the finances of PSG, I don't think all the other teams in the league put together can compete against that. They're just way richer than the rest of the teams.
I actually see PSG winning the UCL over Inter. They are a better team, and they perform better. They don't concede many goals like Barcelona, which was the reason Inter were able to knock out Barcelona in the Semis.
