Posting odds for the outright winner (from BC.Game):

I wouldn't be surprised if they changed significantly after the first-leg games are concluded.

For comparison, here are the odds post-1st leg games:

We're most likely to see the English final between Man United and Tottenham, with Man United being the favourite.
Who knows how the Athletic Vs Man United game would have gone if not for that early red card (and a penalty) that set the tone for the remaining 60 minutes. Before that happened, Athletic had a pretty good and aggressive start with a few good scoring chances missed.
Anything is possible in football, but I don't see Athletic coming back from such loss.
As expected, Bodo/Glimt got dominated, but luckily they responded with one goal of their own, so there's still a sliver of hope for them. Maybe Tottenham will get overly relaxed, and maybe the home advantage will work wonders for the Norwegian team in the rematch.
