I don't know Coman. but I know Nkunku was from the academy of PSG and this player came from PSG when he was a very young player. But unfortunately, PSG doesn't pay attention to the younger talents they have, instead, they pay too much money for the players like Mbappe and other superstars, so they have to force them to stay in the team. I think the management system in PSG is wrong and they are the main problem because if they try to use the younger player they had before like Nkunku, they can have a much better performance than this.
That's what other teams do, they try to hire or raise the younger players instead of buying expensive players, which can be a much better and cheaper way for them to have players like Mbappe on the team.
This has always been my concern for PSG they don't seem to look like such a team thst is willing to be patient enough to want to build a team for the scratch and probably get to the point they become so formidable they will be able to be very productive even outside the Ligue 1 but they rather choose to keep focusing on starts with the mind that that's the way to helping them been able to achieve the kind of results they want to get.
If they are willing to build a team using young stars and talents such as the likes of coman and nkunku who were all gotten from their academy, they will be able to get a team thst will give them the kind of results they Desire even if it's going to take sometimes, but in the end it will be worth the wait and it will be even cost effective for them, just like Leverkusen now who's doing so well already and they are getting these results with their own players they did nurtured and not buying stars alone, it's even much better a team is able to build a star and get him to give the team the kind of performance they desire to get and later sell him off at a huge price which will now be another source of income to the team.
The Ligue 1 has always been the only place where PSGs dominance has been felt the most, they can possibly become a better team outside this small league where it seems their prowess is the most if only they are willing to probably risk a whole season to fixing the team and getting the team to produce the desired results and subsequent they would have a reliable team they can actually depend on the getting the kind of results they wanted all along.
