The problem with PSG is that they have a little too much money right now. And they are literally someone who wants to achieve anything with money. We know that is not possible all the time. You can get everything top of the level. But you cannot buy experience with money. You also cannot buy the chemistry between the players that you should have with money. Yes, it was very unfair to Christophe Galtier what they did. They should have given Galtier more time. But as you all know, a rich club who has a lot of money is not getting good enough results and was just trying to make changes to bring in better results. Sadly they do not understand that it does not work like that.
Anyway, Luis Enrique is definitely a very good coach. he has had huge success with Barcelona previously towards the 2016/2017 time period. So if Enrique is given enough time and if he is also given enough money, I think he will be able to bring in good results.
Since when is it a problem to have a lot of money? Manchester City has a lot of money, too. And by the way as far as I know the on average best paid players in Europe are those from Real Madrid. Was a year or so ago when I saw the statistics, so can't exactly tell whether it is the same today, but guys like Kroos earned 20 million at least as a standard. They can afford crazy transfers as well. Mbappe was an exception at PSG and he did it correctly, he just milked the cow as much as he could and PSG made him an almost billionaire.
But too much money isn't a problem. Bad management and bad coaches are a problem. PSG has had bad management forever now and they have had coaches that were an A- rather than an A+. Galtier, who is Galtier? Liverpool wins the Champions League with Klopp, City wins it with Guardiola, Real Madrid wins it with Zidane and Ancelotti. Who the heck is Galtier?

Enrique had an incredible timing at Barcelona. Attacking line was Neymar, Suarez and Messi in their prime. Iniesta, Busquets, Alba, Mascherano etc. I guess there is no need to go on.
