First let's come to Real Madrid vs Chelsea match, Chelsea is one of the best team in English Premier League but Real Madrid will be ahead of Chelsea in Champions League. That means Real Madrid will qualify for the semi-finals between Real Madrid vs Chelsea.
The scenario is that Real Madrid have to win the first leg or maybe draw at Stamford Bridge and settle for a decisive home win in the second leg at the Santiago Bernabéu. If Real Madrid can do it, then I believe Real Madrid will qualify for the semi-finals without any problems.
Meanwhile I don't fully believe Chelsea is a relatively easy opponent for Real Madrid. Chelsea are not the favourites, but they are a team capable of destroying Real Madrid's mission in the Champions League this season. Of course This is worrying, but Real Madrid are the favourites.
Man City vs Bayan Munich In this match I will put Bayan Munich ahead of Manchester City. Because they are very good at countering it.
I hope you are wrong, Manchester City is a good team to fall short in the quarter-finals.
At least that's what I think of Manchester City, but you are entitled to say whatever especially your opinion. Bayern Munich is good, but Manchester City are equal even though they have never won a title in history.
