Massive sweeping statement there about African teams. For a team that supposedly lacks discipline and tactics, they didn't have any problems dealing with the "tactical" and "disciplined" pure European team of Iceland. Lemme guess---they bribed them. After all, they're Africans.
African teams are less disciplined than European teams. As for Nigerian manager Rohr, he said himself that he was shocked how things were when he took over and it took him a while to get used to it.
