A good Six Nations run is not imperative for England and Steve Borthwick, with Chris Robshaw suggesting it will have no bearing on their World Cup fortunes.

Former Leicester boss Borthwick will take charge of the national team for the first time since succeeding Eddie Jones in this weekend's opener with Scotland.

It marks the start of a five-match run that will serve as England's only competitive preparation ahead of September's showpiece tournament in France.

But former captain Robshaw does not feel the team need to ace their Six Nations campaign in order to bolster their prospects later this year.

"It is important, but it is not the be all and end all," Robshaw told Stats Perform. "The World Cup is a separate tournament.

"Of course you want to win, and you want to play well now, but you've still got another four or five months before that.

"I think when South Africa won it back in 2007, they were pretty awful in their build-up.

"You want to be confident going in, but it's not everything."

England head into the Six Nations as underdogs, with France and Ireland the leading favourites to take the title in March.

Robshaw feels there is still a successful campaign to be had, however, pointing to the growth and experience they will develop alongside Borthwick.

"They need to hit the ground running against Scotland," he added. "First and foremost, they need to do that.

"From an output point of view, if they could win [against] Scotland and Italy, and then nick one of the Ireland or France games, I think that will be viewed as a very successful campaign.

"This is a growing squad. It is a new group, but I think it's a great combination of a team [with] huge excitement, experience and a well-balanced coaching staff."

Eddie Jones will make an immediate impact on his return to Australia, for which "there was always writing on the wall", according to former England captain Chris Robshaw.

Jones was dismissed by England in December but replaced Dave Rennie as the Wallabies' coach on Sunday, taking up a role he previously held between 2001 and 2005.

Defeats in November to France, Ireland and particularly Italy proved the final straw for New Zealander Rennie, paving the way for Jones to return in time for the 2023 Rugby World Cup.

The Australian was in charge when the Wallabies lost to England in the 2003 World Cup final, and Robshaw always expected Jones to return in a bid to complete unfinished business.

Speaking on behalf of Sage, powering the Smart Ball at the Six Nations, Robshaw told Stats Perform: "He was a proud Australian man and I think there was always writing on the wall that one day he will be back in Australia coaching.

"They're in a bit of a tough place in terms of their confidence. They had a tough tour in England, and it's no doubt he'll be able to go and shake things up and have an immediate impact.

"It is his man-management, which is brilliant, and his ability to get the best out of people because they have a good team and they have some good players.

"But how do you turn it around quickly and generally? That's all kind of up in the air."

Jones will aim for glory at the World Cup in September, having led both Australia and England – in 2019 – to the final as well as defeating South Africa with underdogs Japan in 2015.

Former British and Irish Lions captain Sam Warburton believes Jones wants to be on the biggest stage to shine, as does Warren Gatland, who made a similar return to retake the role as Wales coach.

Warburton said: "I like him, and at least in the same way as Warren [Gatland], they're international coaches. They need that international kick.

"I can't imagine Eddie being a club coach anymore, same with Warren. I think Warren wanted to just be back in the international helm and Eddie wants to be back in the international helm.

"In front of 80,000 people, he will turn to a press conference of people talking about pressure, he'll be laughing inside, he wouldn't be doing the job this long at such a high level if he didn't truly love it.

"I really respect him. He's gone straight back into the deep end with international rugby with Australia, and he's got a World Cup; that's what he needs to thrive, so it is not really surprising.

"If you said in the Autumn Series, Warren Gatland and Eddie Jones are going to clash somewhere in the World Cup, then you'd be thinking how was that going to be. 

"I don't think anyone would have thought it would have been Wales and Australia. Compared to where we were three months ago, it is a great story, and it's going to develop a great subplot going into the group stage of the World Cup."

Chris Robshaw is convinced Eddie Jones remains the right person to lead England at next year's Rugby World Cup and drew comparisons to Gareth Southgate's success in football.

The Australian endured a difficult November campaign, with defeat to South Africa in their final game capping a worst calendar year performance for the team since 2008.

With the sport's showpiece tournament set to kick off in France next September, England have 10 months to try and play their way into form and go one better than their run to final in Japan in 2019 where they were downed by the Springboks.

Robshaw acknowledged it has been a bruising year for England but believes Jones is the right man for the job, likening him to Three Lions boss Southgate, who has defied critics twice in major tournaments.

"I have been in these situations and the autumn can be tough because you are playing against the best teams in the world," he said at the launch of the Robshaw Kerslake Foundation he has set up with wife Camilla.

"It is about taking your medicine and thinking, okay, in this competition and in this series we weren't quite good enough, but we can come back stronger.

"We also have to learn to move forward, you can't look down on it too much because there are still positives to come from it, and we need to think about how we can be better next time we meet.

"They were saying the same thing about Gareth Southgate and the England football team and now look at how they have played in this World Cup, they have been superb so far.

"In sport, things change very quickly, and I very much believe Eddie is the right man to lead the squad.

"From my experience, he is the best man-manager I have ever worked with and his ability to make players better and better.

"He is someone who will definitely go away and study what went right and very much importantly, what went wrong and why it didn't work.

"He will want to go back out there and prove people wrong, and I have no doubt he is the right man."

Former England and Harlequins rugby union captain Chris Robshaw has announced his retirement from the game at 36.

The back-rower, who traditionally played flanker for club and country, has brought the curtain down on a career stretching back to 2005.

Robshaw, who won 66 international caps, made his Test debut in 2009 against Argentina, and took the armband for the national team in 2012, leading them through the 2015 Rugby World Cup on home soil.

Injuries restricted chances after he was replaced as skipper by Dylan Hartley, and he was phased out before the 2019 World Cup in Japan, and finished his club career in Major League Rugby with San Diego Legion.

"After 18 years of professional rugby and a career I could only have dreamt of, I am officially announcing my retirement from the great game," Robshaw wrote in a statement posted on Twitter.

"Following three dislocated shoulders in quick succession, my body has told me to blow the final whistle.

"No words can do justice to how fortunate and privileged I am to have enjoyed a career in the sport I am most passionate about.

"Playing for and captaining England has been the greatest honour of my life and there is no comparable feeling to representing and leading your country.

"It was a responsibility I approached with respect, optimism and determination and I hope in the coming years I can use my experience and knowledge gained to support other players on their journeys."
