I understand PSG's mentality. The aim is big names, huge wins. However, relying on a few superstars is risky. Huge risk. Spends a fortune, and no trophies? Disaster. Absolute disaster. Mbappe, a terrific player, shows that Champions League pressure can break anyone.
Believe me, this play is smarter: Create your own talent. Slow, but builds a stronger foundation. You avoid outrageous transfer fees and inflated salaries and get players who compete for the shirt, not just the salary. Mixing one or two major stars with local talent? The mixture is potent. PSG needs competitiveness and sustainability to win. Much smarter than their current plan.
I think PSG has learned their lesson the hard way. The club has spent so much money on expensive top-class player to win the Champions League but all their efforts have been fruitless. It seems they are smarter now and it has affected the recruitment pattern. They are no longer interested in signing big names this is why we have not had any reports of targeting big players besides the rumours of signing some players to replace the departing Klyrian Mbappé. They have also disposed of many players which is costing them much. Just like Real Madrid PSG is now interested in grooming younger players because they are cheaper, loyal and can easily blend with the team.
Did you know that I don't think there is anything wrong with Mbappe's current relationship with PSG? They didn't realise that a star player shouldn't play for just one team, and Mbappe deserves all that he is doing. PSG always believes that money is everything, but they also don't realise that money can never buy happiness or a person's career. Mbappe deserves to win a lot of trophies, and since he is still young, he should win them all. I don't think he could play as well at 27 years old.
Yes, as you said, PSG has learned a lesson and deserves more. PSG is one of the teams that spends a lot of money on players in order to secure their signing. I recall that when PSG wanted to sign a player, no team could match their offer because they paid a lot of money for the player. I also think that PSG will learn how to acquire players and develop them into better players as a result of the MBP issue. Real Madrid is the best team that consistently understands how to acquire players and develop them into valuable players, even if they intend to sell them.
