Maybe I'm wrong , but I could image that Croatia will allow Poland to overun Croatia easily in order to eliminate germany as potential opponent in future stages of the EM.
After Croatia beat Austria they would also love to see Germany eliminated, just for tonns
spitefulness.
There is a need of more than two goals and I'm convinced that Croatia who is allready quallyfied will give them the 3 points and probably more than two goals.
That means of course, that Austria have to beat Germany and Poland must be in advance of 2 goals.
Poland vs Croatia:
Win for Poland by more than one goal difference
Betfair 2.40 - 3.95 - 2.96
