What a performance from PSG! Total control of the game from the 1st minute until the 90th+, Real didn't know what happened, they didn't even manage to score! Now, Chelsea will be the last obstacle for the undisputed best team of this year/ season. Xabi Alonso needs to do a lot and change more than that if he wants his team to be among the favorites for the next season's CL. Congrats to PSG, amazing and flawless game. 
Xabi Alonso faced his most serious test. I think playing this match was a great opportunity for them, as it gave them the opportunity to thoroughly analyze the team's shortcomings and areas for improvement. I'm sure Xabi Alonso will take a video of this defeat, analyze it for a long time, and have the players focus on their weakest points. Of course, it would have been better if they had advanced, but there are some losses that help a team reach a higher level. In my opinion, the match they played today was one of such.
