Former All Black hard man Richard Loe attacked Australia's front row before Saturday's Bledisloe Cup Test, claiming the trio lacked heart and performance.

Loe accused hooker Michael Foley of having no heart, prop Richard Harry of being a non performer and said newcomer Fletcher Dyson had proved little. Loe said the All Blacks had nothing to fear from the Australian scrum at Stadium Australia, despite Harry and Foley being World Cup and Bledisloe Cup winners.

The veteran prop of 49 Tests from 1987-95 said New Zealand's all Otago frontrow of Carl Hoeft, Anton Oliver and Kees Meeuws would be too good for the Wallabies, "because I just don't rate the Australian front row".

"They're in dire straits if they can't find a better hooker than Foley. His attitude, heart and everything is missing there," Loe said. "Richard Harry is just filling the shoes waiting for someone else to come along. He didn't perform all Super 12 and he's never performed.

"The other young fellow (Dyson) is just fresh on to the scene and hasn't shown much either. I would expect the All Blacks to dominate up front."

An unimpressed Harry was unfazed by Loe's comments.

"It doesn't need a reaction, that sort of comment," Harry said. "The beautiful thing about it is whoever wins out on the field has the last laugh.

"All the talk off field doesn't have any impact whatsoever on what goes on on the field, that's where the business is done - out there tomorrow. What did anyone think of Richard Loe? He's just another prop."

Harry was, however, more complimentary about his opponents, saying Hoeft, Oliver and Meeuws were a powerful unit forged on years of playing together.

"They're consistently picked for the All Blacks because they are a very, very good front row and they've proved that," he said. "They played very well in the Super 12 and very well in Test rugby as well, so it's another hard day at the office."

He predicted the All Black pack would be more mobile and skilful than the tough Argentinians who bullied the Australian scrum in the Wallabies' narrow second Test win in Canberra last month.

"Argentina did their homework, they attacked a perceived weakness and I don't think we reacted very well, particularly in that second Test. Hopefully we've learnt something out of that," he said. "In the Bledisloe Cup there's no room for weaknesses anywhere, either in your set plays, your phase plays or your attitude. You've got to be switched on the whole time."
