PSG should understand they need to have a more stable situation if they want to achieve anything in the important tournaments like the Champions League but currently, they don't have any stable situation and during the last seasons they were every time about to lose some of their superstar players and let's say in an unstable situation in this team is one good reason for some payers to don't trust the performance of the team and leave.
For example, I think if Mbappe was thinking about PSG winning the Champions League he would never even think about leaving this team but currently is still unsure and there is a high chance for him to leave and in this case, PSG will be in the harder situation.
The stable situation that PSG expects will still never happen if they are still the same as now because after all the problem in stabilizing a club starts with the club management and their strategy in advancing the club but until now PSG does not have that.
They have great resources and strong encouragement from Naser AlKhelaifi in financial matters but club management and officials find it difficult to maximize that into something profitable for them because they only rely on simple thinking where money can buy expensive players and hope to improve their performance.
But in the end it also cannot be done because what is needed is not only expensive players but good management and coaching. Currently the PSG squad is still very luxurious, it's just that seeing the capacity of the coach in the last few seasons is actually ordinary and now Enrique is trying to change the system but it seems that this is still very difficult to do.
