Theoretically, the Spain U21 team is first in a group with a draw. In this case, Italy U21 shouldn't win for more than 3 goals difference.
The reality is totally the opposite. Spain U21 team is a lot better than the Czech Republic U21. They are one of the favorites for the final win and I think they can win today with a 2-3 goals difference. The Czech Republic will try to hold results 0:0 as long as possible, but I think they are not quality enough for a surprise here. We need to know that they didn't score any goals in this tournament. In both matches, it was the auto goal.
All in all quality difference is too big here and odds are too good to miss it.
