bet on Argentina or Portugal seems to be a smart move since I see both them will qualify to the semifinal. Semifinal will be pretty harder to bet since it must be the best of the best teams that still survive.
I hope you didn't bet on argentina, they are a shitty team, currently they are really close to losing against the netherlands and the chances of them losing against the netherlands are very high, I would say that the best thing to do is bet that the netherlands will pass for another phase, I don't see the netherlands losing in this game, and about portugal in my opinion they won the game without many difficulties, portugal is a very strong and well organized team in defense and attack, morocco will not have many chances against portugal, so betting on portugal is a good option
