PSG's weakness is an attraction that cannot be fully resolved because it is not easy to be in a situation where every season you are only motivated by chasing the Ligue 1 title or other domestic titles and that is the reason PSG always lags behind other top European clubs. They only rule in France and when they leave their comfort zone they are no doubt like prey that must be hunted by other great predators.
Using a new strategy in a match such as against a weak Revel team in the Coupe De France competition is not wrong, but of course the results will be different when this strategy is applied against a team that is quite strong or equal. So I think it's not a matter of strategy but more about having fun because a typical big team like PSG only looks great when it's like this and when playing against other strong teams in Ligue 1 they aren't necessarily able to do that.
In the end, we also know that until now PSG has still not been able to maximize the resources they have and the depth of the squad which is still very luxurious until now and things like that still don't seem to be able to change because after all what is happening now we certainly understand that PSG cannot do much for their performance problems and cannot take into account themselves in big competitions like the Champions League so that in the end from each season that runs only Ligue 1 alone they can always master but not with others.
I think the management thinks too simply by wanting star players then they can rule but in the end being in a big competition is not that simple so PSG should know that they need to make some improvements not only in the player sector but in other sectors including their management.
