The odds (by 1win) for the outright winner are in and are as follows:

They are sorted in alphabetical order, not by order of odds, but the top 5 favourites are:
PSG x6.0
Arsenal x7.0
Bayern x7.0
Barcelona x7.0
Real Madrid x7.5
so no surprises at the top.
Do you guys see any potential dark horses here? i.e. any club with odds of at least x30 that would have say more than 5% chance of winning? Inter is looking fairly good. They look like they could be a bit underrated.
I think the championship odds are very good. If I were to place a bet based on these odds, I’d choose Real Madrid or Bayern Munich. If I had to pick one more team, it would be Barcelona.
I don't think PSG will win the championship this year.
If I were to put 100k on each of these three teams separately, I’d make a substantial profit if one of them won—but that requires having a lot of money and the patience to wait 7 or 8 months.
Let's place a virtual bet right now: I'm betting on these three teams. The outcome will be decided on June 5th.
