World Cup 2014: Ardiles has concerns over Argentina defence

World Cup winner Ossie Ardiles is worried about Argentina's defensive line-up ahead of their Group F opener with Bosnia-Hercegovina.

But he adds they look good going forward, with the potent attacking threat of Sergio Aguero, Gonzalo Higuain and Lionel Messi.

Ardiles, who won the 1978 World Cup in his home country, goes on to admit that he didn't enjoy playing in the final.
