Predicting who will win the UCL is not that easy, but also easy at the same time. I agree that there are few teams which can win it, so it is not like there are 30+ teams that we need to calculate, not all that goes to UCL have a chance, most of them have very little chance.
However, if we deal with something that is ab it smaller, and focus on the teams that can actually win it, then it becomes harder. Just look at last year, PSG won this season but they also won last season and last season was even more unpredictable than ever. Because they barely made it into top 24 on the last game, they were out all the way until last game, they got lucky and got into top 24 and then suddenly they beat everyone, on a year where they lost Mbappe, and barely made it into top 24, nobody gave them a chance and yet they won.
Its very hard to predict any team who can win the UCl next season but base on the team transfer and player you can predict it a little bit not very accurate but i can say you can predict the semifinalist at this technique. Psg is the team which are still look strong and the way lucho made this team mentality was just incredible they are still strong and to be the favourite for the next season as well . Arsenal are also in my favourites list. As of till now the transfer window are just open and barcelona and madrid are heavily involved to bring some good player so we can't ignore barcelona and madrid in the favourite list. I just think only 3 team from Premier league can survive next season and it will be Arsenal, Liverpool, Chelsea.
