So far there is only Mbappe who really looks dominant and has made huge contribution to PSG, in fact they have been able to continue winning Ligue 1 for several seasons, especially this season thanks to Mbappe being with them.
For other competitions such as the UCL, I don't think PSG really has enough performance or strength to compete and be able to win the title in the upcoming match, it is certain that PSG will fail to beat Barcelona away and they will be eliminated.
They can repeat this next season but PSG is playing without Mbappe and there is no certainty about who will replace him, clearly this is detrimental condition for PSG.
Yes and the decision to move to Real Madrid was the right decision for Mbappe considering that with PSG he also did not win any titles except Ligue 1, he is great young player and it would be shame if his career did not develop.
It time for Mbappe to go and pursue what he should have gotten long time ago, Mbappe biggest wait is to be able to fight for and win the UCL title, and with Real Madrid the chances are quite big to achieve that.
I am not saying that it is true word for word and every price, but to be fair, Transfermarkt shows that Mbappe is worth as 180 million and total value of PSG as 1.02 billion euros. By comparison, the closest team is Monaco with 347 million euro. Meaning, if Mbappe were to leave today, and you drop whatever remains to half, it still doesn't go under Monaco, they would still be the leader.
This is of course the value, just because you have a higher value, doesn't mean you will win, the year when Lille won, did PSG have lower value? Of course not, but I think putting all of the achievement to Mbappe is wrong. We will see what will happen next season, Mbappe will be gone, and I bet that PSG will have an even easier win for sure.
I don't know what happened but indeed finances will always be determining factor in building team to be able to appear with perfect strength and be able to compete to surpass other team, I believe PSG is the richest team and they have all the supporting factors behind it.
But when Mbappe leaves, PSG will lose that value because this means PSG has lost one strength, maybe they can bring in another player who is much more expensive but that will not guarantee that they will be much better than Mbappe.
Strength of team on average only focuses on one or two core players and most team always experience conditions like this, whatever many people say, but with Mbappe leaving I sure PSG will still have declining performance.
This is not as easy as what you are talking about, look at what the future will be like and I very sure that what I say will definitely happen.
I won't say how the competition was few season ago when LOSC became champions because this was quite long time ago, around 4 years ago and we are here to talk about the future of Ligue 1, especially PSG, which is the best dominator in this League.
