PSG owner is rich enough to hire the best players in the world and they hired Messi the last time, I think this time it's time for them to pay more attention to their coach and they should hire a better coach by spending more money and then PSG can start hiring players to replace with Messi and Neymar for next season based on what the coach ask them to hire.
There are also many unemployed coaches in the world they can hire and I think Zidane can be the best option for PSG for next season.
