League 1 is a very weak league and PSG doesn't have worthy competitors. PSG's dominance won't end here and they have enough money to buy a new good striker, not someone of Mbape's level but there are many other good ones that don't cost a fortune and still play well. PSG will remain dominant in League 1, no one can acquire better players than them.
It's really interesting how PSG's dominance in the Ligue 1 doesn't center only around their performance but also with their financial ability too, they have been able to dominate the whole of the Ligue 1 with their form, financial strength and team dept and that has always kept them ahead because most teams in Ligue 1 are yet to get to such a level or attain such height as PSG and they are not even looking like they would soon.
At some point it begins to feel like the Ligue 1 is becoming too small for PSG to probably participate in the league because they literally at this point determine their fate and not a situation of them having to play or work hard to get the kind of results that will give them a good position or win the League title, they literally get weak at some point and still get back in form again and will maintain their position at the table top with little to almost no threat from others who are equally in the league aswell, but in elite league such as the champions league, their strength becomes unequal as they are now able to compete with teams bigger than them or equal with their strength a s they don't get to enjoy to much of dominance just like that.
