To my surprise, bookmakers are now pricing Tottenham as clear favourites, with Tottenham's odds at 1.61 and Eintracht's at 2.18. Maybe these are inflated expectations for the first game, which will be held in England? It seems to me that if Tottenham do not achieve a serious advantage at home (two or more goals), then in the return game Eintrach will be the favorite.
It was still early odds. I still expect some adjustment to happen when we're getting closer to the matchday. I clearly see how Tottenham odds is most likely moving down, and expect them to have odds closer to the their opponent.
The first leg is gonna a home game for them, and they obviously get a small advantage than Frankfurt.
Yes, usually the odds will change, but it depends on the team performance in their domestic league. Currently, Tottenham is favored by the bookies because they are probably the home team and have more advantages, but looking at their form in the premier league, I agree with you that Tottenham odds are likely to match Frankfurt, I think the current 1.61 vs 2.18 is not balanced. You see how Frankfurt easily beat FCSB in the knockout stages, this means that the Bundesliga representatives are ready to compete to be the title candidates.
