Next season for PSg can be a nightmare if they don't get alternative players for any player they are going to lose, like Messi and Neymar because during this season even with see players they failed to get the results they wanted to get in French League and they failed in champions league however PSG won the French League title but the fact about PSG is they should start seeking for a new coach to gather a stronger team for the next season.
However, they will need to invest even more than this season for the next season to rebuild the team.
PSG will consolidate the team and they have enough funds to do so essentially after the departure of Messi and Ramos from Paris. There is Neymar that seems to be attracted by Saudis since his return to Barcelona is rejected by Xavi. Well I believe everyone in Barcelona will not accept his return that easily..
Paris saint Germain is a rich but failed team in my opinion. Because they can do everything, but they can't get good results from what they do. Before they plan to bring in players to replace the positions left behind, they must improve first, be it from management, coaches and all levels directly related to the team. I think I've seen their problem now, which is bad management.
