“… Argentina 2-1 Bosnia. Alejandro Sabella made the competition’s biggest tactical error so far with his use of a 3-5-2, but he had the intelligence to correct it at half-time. Argentina shape. This match was basically all about Argentina’s formation. Throughout qualification they had one of the most settled sides and formations around, and while they sometimes played a 3-5-2 / 5-3-2 system, this was only away from home, often when playing at altitude. It was a highly defensive plan B. It was very strange, then, that Sabella decided to use that system in Argentina’s opening game.” Zonal Marking
