Sallah is a star player and currently, he is the highest goal scorer. Can someone who is not a star player be leading in goals, that's impossible. I might say that I only see Liverpool winning EPL but I don't see them winning UCL, because there are more strong clubs ready capable of winning the trophy this season.
Why not see them win the Champions League, don't they have a pretty good chance of getting it? They are also in good form right now, so that opens up a bigger chance for them to win the Champions League title this season.
I think all clubs have a chance of getting it, but what makes them different is the percentage of chance they have. Maybe I would agree more when you say they have a percentage that is not higher than other clubs. For example, they have a 30% chance of getting the Champions League calculated from this group stage, but other clubs have a 35% chance, I think that's more appropriate.
