Remember that, in as much as Real Madrid is trying to keep dominating the EUFA Champions League competition, other major participants in the competition such as Bayern Munich, Manchester City, PSG, Dortmund, Inter Milan, and Liverpool aren't happy with that Real Madrid has recently become the dominating team in this game, So they are trying to step up their games too.
Despite Real Madrid recently bringing in of Mbappe into the club, it still not gonna be an easy game for Real Madrid this season.
Other major teams not been happy about the situation of things in the champion's league literally have nothing to do with the performance of both Madrid and those teams, Madrid will keep winning if they don't find a way to get better then Madrid, they will only just stay angry and it will literally not have any much effect on Madrid or even stop them from winning but I know Madrid is very much aware of the fact that more efforts will be put in place by others to get an opportunity to winning the troph, so to sustain their records, they have to continually stay abraced with their form and not dropping their guards down at any point.
