Most of the world as seen on many other discussion platforms and sites are even more on the side of Real Madrid considering the kind of strength they appear to be amassing in the coming season, it's mainly the other teams and ofcourse their fans who will be against Madrid and very likely it will be when they happen to be playing against Madrid, many others will literally be supporting Madrid especially in times when their team isn't playing a game or isn't playing against Madrid.

It's always usually for the vast majority to want to be with and support where strength lays and that's why Madrid is very likely to get the massive support they will be getting from both their original fans and other supporters who may have loved their strength and would want to share in their anticipated victories throughout the season. In the champions league already, most persons are on their side especially those teams who didn't get to qualify for the champions league. Another set of people who will be in complete support of Madrid would be the mbappe fans, they will be supporting Madrid for the sake of mbappe playing in Madrid.

The rest others who will be against Madrid for obvious reasons will also watch Madrid and probably at some point Amy support but very certainly, everyone cannot be supporting Madrid neither can everyone or the world be against Madrid as you did put in the opening of your statement. It's of a good interest that other smaller teams got to qualify for the champions league and they are all going to be equally given the opportunity to compete at the same level with equal privileges .
