The truth is that having that too much players was not doing PSG much good because one of the things I noticed about PSG that time when they have Lionel Messi, Neymar, Sergio Ramos, Mbappe and so many other player, was that it affected the performance of PSG because it was as if there was no much understanding between those players and that was the reason why they were having issues wining matches because of there over squad, if you watch PSG in those days you will observe what I'm saying but since they sold almost all those players that was when PSG were able to come back to there normal performance, so perhaps PSG doesn't need too many players but what they just need is few players that can add to their improvement.
PSG thought that expensive players could give them the Champions League but hopefully, they have learned the lesson that is why they had to let many of these players leave. They are now focused on buying cheaper and younger players. Keeping many superstars in a team will cause personality clashes that could even divide the players among various cartels led by each of these influential players. There was always disagreement between Mbappé and Neymar and this led to so much distraction.
PSG is the most productive team in Ligue 1. They have dominated Ligue 1 and no one will doubt their performance. facing Lens, I don't think it will be difficult for PSG to win. this season they are already leading in the standings and Nice will not be able to catch PSG either.
If Lens could come up with a strategy that stemmed the aggressiveness of PSG's attackers, maybe the result would be different. but it won't be easy. PSG always appears strong, and Lens may have to think about how to make plays with strong defense.
PSG is the most successful team currently in the Ligue One because they have the biggest budget. Before now clubs like Monaco were outstanding but with a limited budget, they could not achieve more like PSG. Lens is not a mediocre club based on the present performance. They have lost just one game in five matches and can be difficult to win. Playing in their home ground Stade Bollaert-Delelis with the support of the fans can also be a plus for them. However, PSG remains the favorite to win the game but a loss will give Nice the hope of catching up on the defending champions.
