The penultimate game of the 16 phase has undoubtedly a favorite, as it is extremely difficult to imagine Argentina losing to Switzerland and remaining outside the quarterfinals. Besides, it is quite rare for Argentina to stay out of 8, since it has only once been blocked at the 16 stage, 1994 from Romania.
The cynicity that Argentina faces this World Cup makes it a big favorite for the cup. They play as much as they need to get their winnings, all with 1 goal difference and all without being killed to give a spectacle to the world or to score many goals. If they give them opportunities they will take them, but they will not chase the rivalry of the opponent.
This, I think, is the right recipe for success for such events. The teams that want to win the event never try to exaggerate and let others steal the lights of publicity as long as they do their job.
The Argentinean cynical game is still waiting today. Now they have finished the group and they can not take risks. Maybe 3-5-2 returns to the premiere, but I certainly expect to see an Argentine that will not let its opponents become dangerous. He will try to control the ball and hold and wait for the opponents to score. And it is always difficult for Messi to come up with the solution.
The Swiss also do not expect to play with the naivety they played in the clubs. Their lesson took it to the crash of France, and now it does not even take them open lines to get off or leave the defense to its fate.
I do not see the game open, I expect Argentina to score at some point and this 2-0 may be fatal. My first thought was the 2.5 under 2.10, but since I was given the best chance of winning the Argentine victory I think 3.5 will come, I'll take it.
