And the former Wallabies World Cup winner is confident that combination will help Tonga do more than just scare their rivals in a stacked group at the tournament in France later this year.

Kefu has spent three months of this year abroad, assessing his stocks plying their trade in Japan and Europe.

“We’re going to have a really good team, probably the best ever,” he said.

Kefu’s wife remains in hospital with a serious wound to her arm but the former Australian World Cup winner has been released along with his son and daughter who were also injured in the machete and knife attack by four teenage robbers who now face various charges, including attempted murder. Kefu has revealed the impact of the horrific incident saying: “You know at times, there’s outbursts of crying. I think the first step for us is just getting back to the house and then we take it day-by-day. The kids seem to be OK, but they still need to be monitored probably moving forward.

Tonga’s 47-year-old head coach, who played 60 Tests for the Wallabies and was part of their 1999 World Cup win, was rushed to hospital with his wife and two of his children earlier this week.

The trio were reported to be injured when confronting three intruders at their Brisbane home in what local police later described as a bungled burglary attempt.

Police allege the trio were armed with knives, a machete and an axe, all of which were used during the attack.

The local boy has been charged with four counts of attempted murder, three counts of assault causing grievous bodily harm and one count each of unlawful use of a motor vehicle, breaking and entering, burglary and deprivation of liberty.

He was refused bail to appear in Brisbane Children’s Court.

Police allege the trio were armed with knives, a machete and an axe, all of which were used during the attack.

A second teenager remains under arrest while the third alleged attacker is still on the loose.

The 'Ikale Tahi could only manage one win over Canada in the last of their three games at the recent Pacific Nations Cup but have three more warm up matches before the world showcase.

Kefu said after a month of training and touring together his players were in good shape.

"We've made some big shifts in terms of weight loss and body fat loss. We also made some huge shifts in terms of intensive running," Kefu said.

"It was important that we get a win considering the last four weeks of training have been pretty tough on the boys."
