A hool of the Hulk was enough for the Brazilian to get into a lot of problems and difficulties with the Chileans and get to risk their penchant for the penalty shootout. Otherwise, we would have an easy 2-0 and an easy qualification in the next phase.
That's how I expect the scenario of the fight with Colombia. I do not see big differences between Chile and Colombia, so there will be no difference for Brazil in relation to the game with Chile. I can see a big difference, that the Brazilians have already touched it once with Chile and now they know they will avoid the same problems from the Colombians.
I do not expect the scenario of the fight to change. The Brazilians will get strong, they will score first and then they will look to keep the result. If they do the same stupidity that Hulk did, they will score goals and run again. If they do not pay any mistake then they will put a second goal in the counter-attack and clear the game.
I see that it is worth a risk in the Brazilian victory over halftime, since if the Brazilians are not the first to score, we may not have any goals in this game, and if the Brazilians do not score in the first half, it will be difficult to take risks then the fight, because the stress is too great for them.
