PSG management should rebuild their squad next season. In the last few seasons, we have seen a lot of star players in PSG's squad. But there is no improvement in PSG's performance. PSG changed coach several times but did not get good results. PSG management should appoint an experienced coach instead of wasting money on buying only star players. Even an average squad can perform well if the coach is experienced. And so PSG's management should look for an experienced coach like Zidane or Guardiola.
It seems that the problem at PSG is the coach because as far as we have seen they have great players in the squad but their performances in the Champions League have been very inconsistent. Christophe Galtier was not the right person to handle PSG and he was not Combine able to mix the existing players and even at the end of the season they were not very consistent. Although in the end Christophe Galtier managed to present the Ligue 1 title for PSG this season, in my opinion it was not a big achievement because previously they were candidates who often won Ligue 1.
Zidane is also rumored to be coaching PSG next season but some media say he has turned down the offer and now there is news that PSG are considering Jose Mourinho but so far no word on the extent of the approach they have built with the Roma coach.
PSG is losing Mbappe and they lost Messi too, I think this team is losing the superstar players they had and I think there is even a possibility to say the PSG owner is disappointed with this team and they are going sell the players and try earning money from the players they sell there and decrease the salary they have to pay.
Money is not a problem for PSG's owners because the club's owners own everything and I think it's completely management's fault in managing the club. Nasser Al Khelaifi is a very rich man and he is not looking to make money by selling players because before they have spent a lot of money buying players. So far there have been no reports from any media about players' high wages and the management will try to reduce the players' wages.
