A good comparison by comparing 2 teams from England against Real Madrid. But in a match comparing 2 different teams might not be too precise. I mean maybe one of the teams looks better but gets a bad result against the same 1 team. It should also be considered that maybe one other team has the formula to hold that same team's strategy.
Chelsea when facing real madrid in the champions league there will be a slight difference in their team because Chelsea will play under the tutelage of Bruno Saltor who has a little difficulty predicting their game because Chelsea under Saltor direction may be that they will perform better. Indeed, Real Madrid met again with EPL representatives Chelsea in the quarter-finals after Real Madrid met Liverpool in the last 16. I think this is a pretty big chance for Real Madrid in this match because in terms of the performance of their opponents they been relatively unstable lately.
if real madrid again manages to beat chelsea in the quarter-finals i'm sure they will be strong candidates in the title race. manchester city will face bayern munich for sure this is a big match full of stars in both the biggest teams in their respective league.
