Yes Manchester City and their fans did not respect Real Madrid enough and that was big mistake. When they are playing against team like Real Madrid with their great history and skilled players and ability to keep fighting they can not relax and think they have already won. They have shown many times that they can come back in amazing ways and Manchester City got caught off guard. When team becomes too confident and comfortable they can start to fail and that is what happened to Manchester City at worst possible time. This is tough lesson for them to learn but it is one they will probably remember for very long time.
Man City and its fans seemed too quick to feel happy about the superiority they had at that time in the match and made them forget that the match was still going on and the team they were facing could possibly do something surprising and turn things around. And indeed all that happened. Where Real Madrid managed to turn things around in a very short time. And in the end everyone was silent over the defeat. The joy felt by Man City fans did not last long in this match. Well, we have to admit that Man City has also played very well. Unfortunately they couldn't maintain this good performance until the last minute.
Real Madrid really showed their true strength in the final minutes of the match. And even in the second leg when Real Madrid is the host, it looks like it will also be more difficult for Man City.
