I was surprised when Real Madrid failed to score a single goal despite their attacking style. It wasn't PSG who had a strong defense, but Real Madrid who couldn't create many chances. Regardless, this 4-0 defeat was quite embarrassing in my opinion.
On the other hand, PSG must also be acknowledged as being in top form and full of confidence after their achievements last season.
For Xabi Alonso, he may need to make significant changes next season if he wants to win the title. It's already clear that Real Madrid still has many shortcomings, and Xabi Alonso's tactics haven't been able to create a well-organized team performance across all lines.
I don't think that's entirely true because if you watch the match, you can conclude that PSG's defense looked much better and they were always ready to break down the attacks Real Madrid tried to build.
This shows how important a coach's experience is, because I'm sure Luis Enrique understands which positions need to be guarded more tightly so Real Madrid can't create scoring opportunities.
PSG's performance was outstanding in this match. Although I initially doubted they could beat Real Madrid, they proved it.
Xabi Alonso has not fully adapted well because when facing a much more balanced opponent, their defense actually looked uncoordinated so that the opponent was able to score 4 goals without reply.
