Acasuso (l) says there is no need for Hewitt to employ minders

Hewitt, who has had several rows with Argentine players in the past, has employed two security guards for the hotly-contested tie in Buenos Aires.

"Hewitt seems to think that he's come to Iraq," said Acasuso.

"But we're not bothered because this is the circus that he wanted to set up. Nothing's going to happen and we shouldn't pay any attention to it."

Acasuso says Hewitt's decision to employ extra protection will not affect his team's focus ahead of the tie, which starts on 22 September.

"We're just worried about Argentina," Acasuso added. "Whether Hewitt has one bodyguard, or 500 bodyguards, that's up to him."

Hewitt has a history of confrontations with players from Argentina.

Juan Ignacio Chela, who will play this weekend, was fined for spitting at Hewitt at the Australian Open in 2005.

Hewitt also had a verbal spat with Guillermo Coria during an ill-tempered Davis Cup singles rubber in Sydney last July.

Argentina, who beat holders Croatia in the quarter-finals, are favourites to win the tie at the Parque Roca, where a capacity 14,000 crowd is expected on all three days.
