By looking at the last few matches between the two teams, both Real Madrid and Chelsea, I am more confident that Chelsea will qualify for the next round.
I think Real Madrid beat PSG because PSG players made a lot of fatal mistakes, causing defeat, more precisely Real Madrid won because of luck, but on Chelsea's side it was because of the quality of their football game, which was very good.
The Chelsea squad may not have the star players like PSG. But there are excellent bonding between their players. PSG's match strategy was very bad. At the same time, the understanding of forwards' player with the midfielders is not good, that why Real Madrid beat PSG 3-0. But Chelsea is very strong as a team. So Chelsea will not lose against Real Madrid. They will be able to qualify for the next round.
I think it will be really amazing if Real Madrid can win this match against Chelsea. because almost everything points to Chelsea's win in my opinion and the only thing that is probably in Real Madrid's favor is their ability to play great football in the Champions League. Other than that I think in almost every other aspect Chelsea is better than Real Madrid.
