Although PSG's attacking side is fairly good, I don't see any improved players in the team from midfielders to defense. The PSG team performed poorly last season as well due to the only midfielder and the defense in these areas the PSG authorities need to do a great job.
PSG will not get stronger if there are still weak lines in their team, because last season it was clear that PSG would not be successful in the UCL when they only relied on their front line, while the other lines were still not strong enough. So that is still the main task of PSG if they want to make their team stronger this season, because defense is a very important line for all teams. And this season everything is also clear where PSG was only able to draw in the first two matches in Ligue1.
