Hi mate. I don't know about this, it seems a few of your facts are wrong.
Firstly, no team has locked up any position in this group. There are 3 games left for Iceland and 4 for Germany and all spots are up for grabs. Czech republic are ahead of both Iceland and Germany as for now. The group winners and four best runner-ups go to the playoff.
Germany should probably care because they are the reigning U20 Euro champions and recent years they have been one of the strongest teams of all on youth level. Easily brushing aside favourites Spain and England in last summers EURO for example. And they are in a poor spot with not that many games to go.
All that being said, I still think the
odds on Iceland are a bit too big. I might take a small punt on them. Over 3 goals looks a certainty as well, and might be worth it priced at 1.775. Probably I'll take the latter one and then leave this one alone. Both teams are scoring like crazy.
