The current odds for the Champions League trophy are as below.

Liverpool are the biggest favourite which isn't odd to see. Barcelona-Arsenal-Real Madrid trio are given the same chance for the trophy as you can see too. Despite Real Madrid's problematic start to the league phase nothing changed for bookies.

This is mainly due to Real Madrid's literally owning this competition with most trophies by far. They surprise people even in times of struggle. How do you see it? Who is your favourite?
For now I have no favorite and I see this season's champions league winner as a club no one might expect to carry it. Heck, Man City could even come from their struggles to take it because at this moment no one is expecting them to because they are going through a rough patch but don't be surprised that if they win Club Brugge their morale can come back. We all know how much of a fighter Pep Guardiola is and if he could defeat Chelsea in their domestic league, the Belgian outfit may just be a walk in the park.
Liverpool have the greatest odds of winning the title because they've not lost any of their games in this competition but fate has its way of fucking with this kinds of records as it could be that if they make it to the final, they may get sent packing by their opponents. Take the example of what happened to Bayer Leverkusen in the Europa last season.
