I've always thought that the Argentine team had a lucky draw to get to the knockout stages. This game against the Swiss just showed how poor their team play really is.
Sabella keeps changing their formation, too: 5-3-2, then 4-3-3, then 4-4-2, which is probably confusing his players.
Argentina, on paper, has the most lethal strike force of any nation, with Aguero, Higuain, Di Maria, and Messi. But the tactics have been poor, and the supplier to this fab four, G@go, has also underperformed, imho.
They are very reliant on the heroics of one man. The funny thing is that these are very similar circumstances to 1986.
