Czech have unimpressive group matches and they are not my choice. Netherlands are my choice but I don't believe that Czech will give Netherlands an easy match to play.
They will try to bring troubles to Netherlands and Austria yesterday controlled Italy very well. They did not give up their match too soon and too easily. Netherlands will need to very concentrate with defense system and their attacking system must work exactly. Delay should take chances better to score goals. He is the play maker of Netherlands and also a best scorer for them.
Croatia are not weak and they have better quality than Czech.
Netherlands will certainly win, they are the much much better team right now and they are not going to end up losing to a team like Czechia, the difference is staggering.
However if I had to defend anyone that would wager against Netherlands for that game, I have to say that it is quite easy to lose a game of elimination, if this was like an NBA series where teams play 7 times I would say it is impossible for Netherlands to lose it, but in just one game of elimination with scores so low, there is a chance Czechia could get very lucky and win, is it the possible outcome? Of course not, everyone expects Netherlands to win, but that doesn't change the fact that it is also not impossible neither and anyone who wants to take that risk should. If it was impossible there wouldn't be a bet, obviously people do bet on them since there is still an odd for it.
