England fans might not know the name Marika Koroibete just yet but they will do by the time the final whistle goes at Twickenham according to Australian legend George Gregan.

Former rugby league superstar Koroibete came over to union from the NRL this year having played for the Melbourne Storm and the Fijian-born 25-year-old will start against England for the Wallabies on the wing.

In the absence of another cross-code star Israel Folau, who has been rested for the Autumn Internationals, Gregan believes Koroibete could be the X-factor for Australia having already scored four tries in five Test starts.

“Marika Koroibete has had an outstanding year and he looks more and more comfortable every time he plays a Test match,” said Gregan, who won 139 caps for Australia.

“He’s a wonderful finisher so although they’ve lost Israel Folau, that back three is still very dangerous.

“Koroibete is an electric player, he played for the Melbourne Storm and they were one of the best rugby league teams for a decade in Australia.

“He was playing with the likes of Cameron Smith, Cooper Cronk and Billy Slater so he knows how to finish and he’s got that winning mindset too.

“You’re seeing him adapt and look really comfortable in Test match rugby and that Test intensity. He’s also a hard, strong defender and an incredible finisher in tight spaces. If he gets opportunities people will remember his name, that’s for sure.”

Australia arrive in London fresh from yet another win over Wales – their 13th in a row – but it is England who have dominated recent meetings with their antipodean rivals, winning the last four.

England’s last defeat at Twickenham actually came against the Wallabies when they were knocked out of the 2015 World Cup, and Gregan expects his compatriots to repeat the trick.

“I think the Wallabies will get this,” added Gregan, who was speaking on behalf of Land Rover, the long-standing supporter of rugby at all levels; from grassroots to elite. This year, Land Rover is celebrating its Testimonial Season, with ten years of support for grassroots rugby in the UK.

“I think it will be really close. It’s me being patriotic but I also think this Wallaby team is a lot more mature and in a better place than they were 12 months ago.

“They can start well, they can come from behind so there’s a real composure and much better leadership across that team. I’d say the Wallabies will win by a margin of less than seven, so it will be tight, but I think they’ll get it.”

In the build-up to the game Michael Cheika has spoken of England’s tactic of late tackles on opposition scrum-halves and holding them down.

For Gregan that is simply part and parcel of the role of a nine, but he does admit that the battle at the breakdown could be the decisive factor in the game.

He added: “Getting after the nine and ten is like in the NFL getting after the quarterback. You want to try and reduce the time and space and decision-making.

“The flip side of that is that if the Wallabies control the breakdown and the quality of ball, that negates the nine and ten being got after because they are on the front foot. So that’s the battle.

“I think the set-piece will be a really tough contest, in lineout and scrum they will be looking to get some advances there but in terms of the winning of the game it will be around the breakdown and the first up tackling.

“The team which does that really well will create some opportunities for them to attack off which is critical in these types of Test matches.”
