Chelsea actually played not too bad.
Take a look when Kante managed to snatch the ball from Modric's feet, Kante didn't hold the ball for long and immediately passed it to Joao Felix who was free-standing, but Felix hesitated to shoot when he was in a one-on-one position with Courtuis.
Not long after, Chelsea immediately conceded through Benzema's feet in the 21st minute using Vinicius' pass.
I think Chelsea's problem lies in attack. Evidenced by the statistics on the number of shoots against Real Madrid.
After Chilwell received a red card penalty, they were clearly having trouble managing the game.
Kante played really good for me in this match and gaved a boost to Chelsea but it wasnt enough. Chelsea has only chance to win something is in champions league and they are too far now. With how bad they are playing i dont see them even drawing the match against Real Madrid.
