If Real Madrid come up to the match against PSG in optimal shape, then PSG will have little chance of making it to the next round in the Champions League. PSG is not a balanced team. They have strong players in attack, but there are not three players in defense at once.
I assume it is difficult to know which team to qualify to the next round. PSG has strong strikers, they potentially make Real Madrid only focus on defending. If it happens, PSG will be easy to create many goal attempts. While Real Madrid players are under pressure and hard to create the chances to score. If Real Madrid wants to win the match, they must win the ball possession and control the match. Benzema, Vinicius, or Asensio also must play effectively and show their accuracy in shooting.
I might have to disagree with that, PSG play better in counter attacks and have difficulties when a team is all the way back in defense, and we have seen that multiple times in ligue 1, especially in the match against Lens, Psg were having a lot of difficulties getting through Lens's defense and we have seen Lens players several chances to score a second goal and end the match but they missed some easy ones, and with players such as Vinicius and Benzima we probably won't see the same thing, Real Madrid was and still one of the best teams in counter attacks.
