However in case of seeing these two very important players leave the team even the right manager would have to deal with some serious problems about achieving their biggest goals. I wonder who would make a new trio with Mbappe in the attacking line.
What problem? PSG had a bunch of money. Searching new players to replace messi and neymar will not become hard tasks to be done. PSG has been tageting several players include osimhen from napoli. It's likely that if PSG will be also increasing its offer to the napoli for osimhen.
The problem is, if PSG is not having a good coach right now to handle the team. that was also making the club has limitation to improve its performance compared with this season. PSG needs to use its money wisely.
It depends on whether they use their transfer budget in the right way not to cause any problem in the attacking line. By saying "problem" I wanted to mean that actually. Because it might not be very easy to build a new trio that can have a great communication style with each other. Messi, Mbappe and Neymar have been getting along really nicely so far.
Even in the times there were some personal issues between Mbappe and Neymar for example, they weren't still reflecting this onto their games. In those times I remember watching Mbappe and Neymar making assists to each other which was a great example for other players.
