I left betting on national teams after the World Cup ended but Germany were one of the best playing teams in the World Cup. They just had issues with finishing and said farewell to the tourney in group stage unluckily. I see Germans as favourites of the tourney with their host country advantage as a result.
Together with France they are definitely the favourites, even if I think France is much stronger (since they manage to put the ball in the goal unlike Germany)
Portugal I don't know, Spain doesn't seem very fit to me
We don't talk about Italy, my national team is in very bad shape, it would take a miracle to get it back on track
