South Africa assistant coach Pitso Mosimane is worried about Mexico's attacking approach ahead of their FIFA World Cup™ curtain-raiser on Friday.

The two kick off the global spectacle at Soccer City having met three times previously, with the visitors holding a 2-1 advantage.

Javier Aguirre's team have made it through the first phase of the last four FIFA World Cups, making them a real threat for Bafana Bafana in a Group A that also features France and Uruguay.

"It will be a big tough game, you know how they play," Mosimane said. "They play 3-4-3 and switch to 3-5-2, and they are very difficult to contain under those circumstances.

"Their system is confusing to their opponents and they are not afraid to throw men forward."
