Several top teams have similar percentages, such as Manchester City and Liverpool, and they shouldn't be underestimated. However, I'd like to emphasize that defending the Champions League title isn't easy, so I'm slightly ruling out PSG this season.
Real Madrid is also a bit questionable, as their early season performance hasn't been impressive. So, I have little doubt that they'll be a fierce contender in this season's Champions League.
So what about Barcelona chances? Or are you leaning towards Liverpool and Manchester City, who were clear favorites last season but were suddenly eliminated? It might be better to wait for all the top teams to appear, as it's too early to speculate let alone doubt last season champions.
You are right mate, it's too early to speculate on who is the favorite club to win the Champions League this season. Manchester City is still struggling to pick form and they were humiliated by Tottenham on clean sheet last weekend. Currently, most of the big clubs ain't performing as expected from them. This has put me into confusion on which of these clubs will make it to the finals.
