I have seen many Chelsea fans happy that they are the favourite to win the trophy, but I just see it as fun because they know that Chelsea cannot defeat Real Madrid or PSG, and for some people who think PSG is going to knock out Real Madrid easily, they should also know that Real Madrid knows how to play any competition, and when it comes to semi-final matches, Real Madrid always surprises people.
At this point any of the teams that are left in the tournament is considered a potential winner of the competition because they are all strong. In a competition were 32 teams came to compete and you made it to the last 4 such teams are to be considered strong. So I don't blame any Chelsea fans that is saying that their team is the favourite to lift the trophy. Sometimes it is not even about a team that is the strongest that will lift the trophy. Chelsea and Fluminense one of the will be in the final and luck could be on their side on the final day and they might go home with the trophy. There is no point underestimating any of the remaining teams, because that team could be the champion at the end of the day.
