Top 5 favorites according to betting odds:
Serbia (+350)
Germany (+400)
France (+600)
Greece (+800)
Slovenia (+1200)
Group A
Group with the biggest favorite in a tournament - Serbia. Serbia is clear favorite to win group A, although host Latvia and underlooked Türkiye will be a tough nut for everyone. Chechia hopes to get in on the action too. I expect theese 4 teams to qualify, leaving Estonia and Portugal behind.
Group B
Germany is a clear favorite in this group. Lithuania could have something to say, but I expect them to be second. Host Finland alongside Montenegro could surprise. These should be top 4 teams in the group, Swedem and Great Britain shouldn't be much of a factor.
Group C
Pretty deep group. Greece, Spain and Italy could all win this group. Georgia and Bosnia & Herzegovina also have talent. If I had to pick, I would say Bosnia does not qualify, but this is first group were top 4 teams aren't clear. Host Cyprus should undoubtfully end up last.
Group D
SImilar to group C, gorup D has 5 teams who will expect to be in the playoffs. France and Slovenia are the favorites, but Belgium, Israel and Poland will fight for those last 2 spots. Iceland shouldn't be a factor.
