Carlos Tevez and talented Argentina are up and running in their World Cup challenge after an opening 1-0 Group B victory over Nigeria's Super Eagles in Johannesburg.

Goal-hungry City striker Tevez didn't get off the mark - defender Gabriel Heinze was the surprise scorer just minutes into the game - but Carlos played a substantial role in the win.

While strike partner Lionel Messi mesmerised Nigeria's defence and captivated the crowd, Tevez put in the hard-working terrier-like shift that has made him a favourite with Blues fans.

Argentina's traditional rivals Brazil are gearing up to try to capture their fifth World Cup, starting on Tuesday against North Korea, with Robinho a central figure to their plans.

The City striker has a champion in the great Pele, still an influential figure in the Brazilian game, who warns: "I am worried about Kaka, and this means Robinho will have to take more responsibility."

Robi, with 70 caps, is a major part of coach Dunga's master plan to take home the trophy to Rio, and he will be expected to take games by the scruff of the neck if Kaka is kept quiet.

Meanwhile, Nigel de Jong's confident Dutch side will open their campaign tomorrow in Johannesburg against Group E rivals Denmark, while Roque Santa Cruz's Paraguay face Italy in Group F.
