Argentina coach Diego Maradona admitted his side will face greater tests after their 2-0 victory over Greece at the Peter Mokaba Stadium made it three wins in succession in Group B.

Defender Martin Demichelis and substitute Martin Palermo scored the goals in the last 13 minutes after finally breaking through a determined Greek rearguard action.

"Now the road gets more difficult," said Maradona. "You always hear about Germany, Italy, Brazil playing poorly, but they're always in the second round, quarters, semi-finals and the final."
