In my opinion, PSG is just wasting their money to buy first-class players, but the results of winning the European League have never happened, but only the League Champion is always achieved without strong competitors from the French League, here it is very clear that PSG only raises the Club's name by purchasing expensive players and does not focus on building the club, so it is not surprising that PSG always fails in winning European Cups such as the Champions League or other prestigious trophies, even though they have a president who is very generous in purchasing players, the results they achieve just in vain.
Every team has a different way of building their team and indeed PSG chose the wrong path because they didn't want to go through the process and rely on the power of money they have to buy star players and hope they will achieve achievements on the European stage, that's the wrong thing and Even Mancheter City used to be like that before they finally went through such a long process that it was only last season that they managed to become CUL champions.
Likewise with PSG at the moment, especially because in the French League there are no fierce competitors so PSG cannot measure its strength.
Buying star players and building great squad depth is part of the process for a team that wants to win the title. PSG did it right and they have gone through that stage, but that doesn't necessarily make them successful in the Champions League.
So far PSG have dominated Ligue 1 and that is part of their success in building squad depth so far. The Champions League is a difficult competition, so it is not easy to win even if the squad is good. However, PSG qualified and fought in the Champions League final several seasons ago even though in the end they lost 1-0 to Bayern Munich. It was part of an experience they must not repeat if they qualify for the finals next season.
Looking at the past is a good one but they have to take it gradually, they have to bring in players who are ready to play and fight for Paris Saint Germans. The Champions League is tough yes but it's same Manchester City that won for the first time after so many failures to talk about. This season, they wouldn't be able to win the competition because they don't have a very good squad.
Dominating the League 1 division isn't a bas thing, that would definitely reflect on the Champions League if they have a pretty cool performance..
That season it was narrow win for Bayern Munich ( if I can remember Kingsley Koeman ) scored the goal to set them as winners of that Champions League.
