Holland would definitely want to play Romania again in the later stages than playing with Italy or France. If Holland won over these two it doesn't guarantee the win the next time again. They would prefer facing Mutu and the Nicolaes than facing Toni + Cassano + Del Pie on their good day or Henry + Ribery + Benzema and the rest on their best day.
Plus they will rest their players for the next match without caring for the result, which makes them intentionally not care the result and lose it. No one cares about ethics here I guess, and no one wants to face the best team out there, that's just cheap talks, everyone wants to win the cup badly, and would/should do anything to make that possible.
