Johannesburg - Carlos Alberto Parreira has admitted he will need to tweak his Bafana Bafana side when the World Cup kicks off on Friday.

The Brazilian mentor was delighted to see his charges extend their unbeaten run to 12 games after a 1-0 victory over Denmark on Saturday.

And while he declared his team are mentally and physically ready for the global showpiece, Parreira revealed he needs to shuffle his pack in areas ahead of the clash with Mexico at Soccer City on June 11.

"I only dream about positive things," he said. "But this game [against Denmark] gave me a lot to think about and it is a good thing.

"The good thing is that we have options and I played with a few ideas against Denmark and those left me with a few things to think about.

"We have taken the right path throughout our preparations and only during the week will I make up my mind about who to go for against Mexico."

Parreira has decided to use Steven Pienaar in a central, supporting striker role, in order to accommodate Siphiwe Tshabalala on the left wing - the Everton star's preferred position.

But the country's premier playmaker has not been his creative self in the middle of the park, as he often gets drawn too deep and leaves Katlego Mphela isolated.

Parreira could be considering Pienaar's position, which means either Tshabalala or Teko Modise could give way.

Reneilwe Letsholonyane has established himself as Bafana's first-choice holding midfielder and Parreira must decide whether to partner him with Kagisho Dikgacoi or Thanduyise Khuboni.

Meanwhile, Bernard Parker and Surprise Moriri showed the coach that when called upon, they will be able to do a job for the country, which is exactly what Parreira wants: for his players to make the nation proud.?
