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.
Although you have the freedom to choose but still, the reality is that you will only choose the seeded teams or the existing elite teams like Real Madrid and Manchester City and a few other elite teams. Because after all, even though you have the freedom to choose your favorite team but yes, the reality is that you will not choose Copenhagen and Lazio in your choice, I am sure about that. Because yes, basically we will be influenced by the big names. For example, if you don't know anything about soccer but at the same time you have to make a choice and hear and see that there is Real Madrid there, then I'm sure you will make your choice on such a famous team because their big name is not in doubt.
