Etoile du Sahel of Tunisia beat Mexico's Pachuca 1-0 on Sunday

South Americann champions Boca Juniors have promised to tear apart Tunisian side Etoile Sahel's defence in Wednesday's Club World Cup semi-final.

"We will definitely score goals and win," Boca coach Miguel Angel Russo told reporters.

"Our style is to go out and to score goals. We won't change that philosophy for anyone."

Barring any major upsets, Boca are expected to face Italy's AC Milan in the final of the seven-team tournament in Yokohama on Sunday.

Milan face Japan's Urawa Reds on Thursday.

Even Etoile coach Bertrand Marchand admitted Wednesday's match in Tokyo was almost a case of mission impossible for the African Champions League winners.

"Boca are a massive club and are on a totally different level," the Frenchman said.

"It's an honour for us just to play against them."

Marchand offered similar eulogies to Mexico's Pachuca before his young side produced an upset 1-0 win in their opening match at the weekend.

But Etoile realistically have little chance of achieving a shock victory over Boca.

The Argentine giants simply possess too much firepower - and the game means too much.

"We'll put them under pressure and if they slip up we will punish them," said Russo, whose side missed out on the Argentine championship last month.
