Defending title in Ligue 1 by being the richest team with zero debt because of oil money, well, not really a big achievement. So yeah as I said, they bought talent and won it because of that, not because of tactics, tho last season they showed that tactics with good good talent.
With already very good player resource and with their abundant money, they can improve their squad anytime in either summer transfer market or winter transfer market if necessary. It makes very big advantage of PSG against all competitors in Ligue 1 and they have very high chance of successfully defend their title in Ligue 1. I am surely Ligue 1 title is not their main interest while defending UEFA Champions League title is never easy.
In coming season things are going to be challenging for many clubs because few have the good number of changes and few are going into ground after losing their top tier players this is interesting PSG is still had good depth which will help them for having their name into history books.
I am also expecting them to have another win in coming season, but few clubs are going to create good problems for them which will surely create good entertainment for fans Real Madrid have new coach and Liverpool is having too many changes Barcelona is surely tough challenger.
They almost let their best goalkeeper Donnarumma leaving their club in coming days and I saw they prepared for it with another goalkeeper but I am doubtful that their new goalkeeper can perform better than the Italian goalkeeper. PSG can repeat a big mistake like Manchester United did with David De Gea - they replaced De Gea by Onana who created a lot of disappointments.
