indeed it happened a few years ago. but the Chelsea squad that beat Real Madrid at that time, nothing changed with the current squad. So I'm sure Chelsea will repeat the history of the past few years. because real Madrid's current performance is not the best even though they can beat psg but it's a lucky win.
It is unlikely that Chelsea will repeat their past performances and beat Real Madrid again. Madrid experienced team. Chelsea's performance is not as strong this season as we saw in the previous season. So this match will definitely be competitive. However, the chances of Chelsea winning the home match seem to be high. But I have my doubts about whether Chelsea can win at Bernabeu.
Chelsea have been playing with confidence all season but have not scored much. So it seems that they are out of form or unable to beat a strong opponent... But if you look at the history of their 2021/2022 games, they have only lost 4 or five times... Which may speak volumes about good results! I think they can do it this year too! Although of course there are doubts about it...
