Group A-- Spain should probably win the group, with either Scotland or an improved Norway team finishing 2nd to qualify alongside Spain. Georgia and Cyprus can be stubborn opponents on their day for the stronger teams in this group, but they are no way as strong as Spain, Scotland and Norway.
Group B-- France and the Netherlands should definitely qualify from this group, although Ireland and Greece could provide some tough matches for them. Gibraltar will almost certainly lose all their matches in this group and likely concede many goals in every match that they play.
Group C-- England and Italy will be favourites to qualify, but Ukraine should provide very stiff competition for the 2 qualifying places that are up for grabs. North Macedonia are strong at home, but don't have anywhere near the quality that the top 3 teams in this group possess. While Malta are the whipping boys of this group.
Group D-- Croatia and Wales should qualify pretty comfortably from this group. Turkey are perhaps the next strongest side in this group, but I don't think they've got enough strength to threaten the current Croatian and Welsh national teams. Armenia and Latvia are very unlikely to trouble Croatia and Wales, although they could prove testing opposition for Turkey.
Group E-- Again, Poland and the Czech Republic should win this group quite easily. Albania are the only other side in this group that could potentially be awkward for Poland and the Czech Republic, but really Albania do not have the quality players that the top 2 teams in this group have. The Faroe Islands and Moldova will very likely both finish in the bottom 2 places of the group, as they are really too weak to pose any real trouble for Poland, the Czech Republic and even Albania.
Group F-- This will be a competitive battle for all of Belgium, Sweden and Austria to qualify. Belgium will be the slight favourites, but Sweden and Austria are both very strong national teams who should make this very competitive. So, any of those 3 sides could potentially finish in the top 2 positions in this group. Azerbaijan and Estonia who make the other 2 teams in this group are likely to occupy the bottom 2 places in this group, as they will lose most of their matches.
Group G-- Hungary and Serbia will almost certainly qualify from this group. Hungary have proven themselves to be a really strong national side in recent years and they have beaten some of the best teams in Europe. As for Serbia, they have the talent to qualify alongside the Hungarians. Montenegro and Bulgaria are not as strong as they used to be and shouldn't pose much of threat to Hungary or Serbia, while Lithuania are more than likely going to finish bottom of this group.
Group H-- Denmark should win this group, while I am tipping Slovenia to finish 2nd in the group, ahead of Finland. Finland are the 2nd seeds for this group, but I feel that Slovenia have the talent to perhaps finish above the Finns in this group. Northern Ireland and Kazakhstan will be tough opponents for both Slovenia and Finland though, so we could have some interesting results in this group. However, we can't expect many surprise results from San Marino, as they are almost certainly going to lose all their matches and lose heavily in these matches at that.
Group I-- Switzerland should win this group pretty easily. I think Romania could potentially finish 2nd in the group, just ahead of Israel. Belarus and Kosovo could test Romania and Israel, but they still seem a little bit weaker than Romania and Israel. Andorra are the weakest team in this group and will certainly finish bottom.
Group J-- Portugal look like they will win this group, while any one national team from Bosnia, Slovakia or Iceland could finish in 2nd place. As for Luxembourg and Liechtenstein, they are clearly the 2 weakest teams in the group and we can expect them to finish in 5th and 6th place in this group.
