With almost all of the last group games turning into play-offs for the top 16, this seems to be a final that plays out in the morning. This is certainly a tough match for the Czech Republic and Turkey, but I think Turkey has a better chance of advancing.
Although Turkey lost badly against Portugal, in my opinion, they have the most important players in their squad, such as Chahanugu, Balestiermas and Aydar Guna, two excellent midfielders. In other words, they have more attacking weapons and set pieces to tackle their rivals Czech Republic to advance to the top 16.
In the battle against Portugal, they exposed some defensive problems, such as poor passing and the last goal conceded by Boo's offside failure. However, since the Czech Republic is not good at attacking in this battle, they should be able to win this game. The defensive holes will probably stay in the knockout rounds and will only be a concern if they play a stronger team.
As for the Czech Republic, they must be hoping that injured star striker Berdrejšuk can make it back in time for this battle. What they need is to win a wave. One wave won't be enough for them, so they need to fight for goals, which has been their weakness in this year's competition.
The only result of Czech efforts is a win. I think Turkey will be able to win on a defensive counterattack, as we saw Georgia against Turkey during the course of the tournament. Therefore, they are the ultimate winners.
