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.
I don't think we should totally blame the PSG team for investing so much money on big players with the aim of winning the champions league, the team was so desperate in winning the champions league and as a big team that has got the money to spend I don't think it was a bad idea to buy super stars but they were so unlucky not to have won the same trophy that made them to spend so much money on big players.
If PSG wants to be like Real Madrid in terms of the young players they have they will need to shift their focus of winning the champions league for now while they work on building the team with the young players they are willing to buy.
