Brazil star Kaka believes Argentina will crack under pressure when the old rivals meet on Saturday in their 2010 FIFA World Cup South Africa™ qualifier in Rosario.

Argentina are only fourth in the regional group, five points behind the group-leading Brazilians, and only four teams go through automatically, hence Real Madrid forward Kaka says the nerves will get to Lionel Messi and company as they go all out for the win they need to catch up.

"They are going to start off a little tense and I think this can play in our favour. There are many ways in which we can try to exploit the fact the pressure is on Argentina," said Kaka.

They (Argentina) are going to start off a little tense and I think this can play in our favour,

Brazil forward Kaka.

But he added it would be tough for both sides. "The game won't be easy for anyone - with a Brazil v Argentina match there will be a number of top talents out there with players capable of swinging the match at any moment.

"Our target is to beat Argentina and qualify for the World Cup. It would be ideal if Brazil could go through against Argentina," said Kaka, who will be winning his 70th cap.

Kaka said he wanted to play down his duel with Barcelona's Messi. "I would vote for him today (as world player of the year) for all that he won (last season) with Barcelona. I believe Messi is the big favourite to win the prize as FIFA's best player this year."
