It's not that fans are underestimating Real Madrid, it's that Manchester City have been incredibly strong for the last few seasons, they are going for broke, if you can call it that. Added to that is the fact that these two teams met last season and Real performed poorly, to put it mildly, getting thrashed, so fans remember it all the time
It was an unforgettable match for Real Madrid and this season it was like they were reunited with destiny and had to face Manchester City again. I think this could be an opportunity for revenge and maybe Manchester City won't be able to stop Real Madrid. Sometimes defeat teaches important lessons and Real Madrid realized this when last season they were knocked out by Manchester City. They have now cleaned up and will fight to win back the title they have been eating all the time.
I believe so much in revenge but most times it doesn't work as planned. I cannot also say that they Real Madrid squad that we have now is better than the one that faced Manchester City last season. I cannot actually explain what actually happened in that match with a Manchester City and Real Madrid. The almighty Real Madrid played like and amateur club, they were not good at any point in time. It was a total mess in their record, but then it is true that they can make it right this time around by staging a revenge. But will it be possible, we are very much aware of that Manchester City squad is fully informed and all the key players are not injured, how possible will Ancelotti and his boys deal with Guardiola and his boys. It is better they play the match and becomes fair than for Manchester City to trash Real Madrid for the second time. We have seen that since Bellingham join Real Madrid, many things changed for good in the club. Will that make the difference?
