A team that I consider a favourite today may perform poorly after a while or my favourite player may change. Also, since I have personal freedom, I can keep any club I want on my favourite list. If a team is good I will definitely support it. I'm also not in favour of supporting a team emotionally while people enjoy the game and are there for entertainment. I think my own preferences may change over time. No team should be emotionally supported for entertainment or betting purposes.
This is also what I do, I analyze and determine who will win because I will also include it in my betting list. If later it causes me to lose, that is the risk of a bet that must be prepared to lose. IN the Champions League I am always neutral and judge based on their overall performance, apart from that I will look at the mentality of a club. Because I see in the Champions League the mentality of being one who takes part in the results that the club will get in the future. Because usually a club with a high mentality will be more comfortable in playing, and in a game comfort is something that can bring victory.
Manchester City, Real Madrid are the 2 favorites, Inter Milan is also in my category, apart from that a club like Bayern Munich is also actually one of them, but I personally put a smaller chance.
