I am one of those who hopes Barcelona wins this match. But yes, they failed due to the imbalance of the game. because Barcelona, which was initially superior, apparently had to lose one player due to a red card. And since then the game has belonged to PSG. So it is not surprising that PSG scored a lot of goals against Barcelona. Because Barcelona is quite weak by only playing with 10 players.
It is looking like it. The duel between Barcelona and PSG could have ended differently as I think the early red card against a team like PSG put the game upside down. The whole strategy fell apart for Barcelona and the last thing a team wants is to be a man down against an offensive consisting of Mbappe, Dembele and Barcona. Against a high speed opponent, losing possession of the ball and control over the game is the worst as that it is the best way to keep fast counter attacks under control.
Real Madrid will probably get eliminated unless they have somehow learnt their lesson from last season's game against Manchester City in the Etihad Stadium. I didn't think that it is possible to see two German clubs in the semifinals, but I believe that Bayern Munich has an advantage over Arsenal, since they are playing at home.
Real Madrid really have to learn from the mistakes they made in the previous season when facing Man City. And I hope this time Real Madrid can entertain us. Bayern vs Arsenal will indeed be quite a difficult match for Arsenal. but I can't predict these two matches.
