This the greatest opportunity for PSG to reform their squad since some big names will be leaving the club. They shouldn't make the mistake of buying more super stars, they should just buy good players and Mbappe wil Lord over. This will bring peace and stability in thr team. And if PSG is not able to solve this problem now, they will still go next season unrewarded in the Champions League.
One exceptional leader with other good players.
With current situation most chances management understand they can't buy trophies with having stars in their squad they need to have better players which give them good results with consistency and also have good skills for doing things better in all competitions their mistakes are bringing problems for them even having few top ranked players in squad they fail to bring any positive change and Champions League trophy as well.
Mbappé alone is enough with have good support which bring improvement specially they need good play-maker even Messi was available in last two seasons but sadly still they were not able to have positive results which was expected now after many big names leaving, hopefully they will try to have players which make good mark for them.
