ENGLAND lit up the Six Nations with their attacking flair and eye for the line - and captain Chris Robshaw believes that is the final piece in their World Cup puzzle.

It was fourth time unlucky for Stuart Lancaster in this year’s Six Nations as the head coach guided his side to yet another second-place finish.

The championship will be remembered for its frantic and thrilling finale, as Twickenham witnessed a 90-point thriller between England and France, only for the hosts to fall narrowly short.

Robshaw, though, is quietly confident England used the championship to tick an important box.

With 18 tries across five matches, England established themselves as the northern hemisphere’s most potent attack.

And, with the days ticking down to a World Cup on home soil, the skipper is purring at the attacking options at England’s disposal.

“You look at the way our attack has taken shape in the last Six Nations and I think that was the biggest thing we really had to add to our boat,” said Robshaw.

He was speaking at Rosslyn Park Rugby Club to endorse the Lawson Keys National Rugby Awards, which will honour clubs, players, coaches, volunteers, mini sections, supporters and many more people that make rugby the fabulous game it is.

“We are almost into camp now, and once we are there it will be extremely intense and extremely challenging, but it’s a place you want to be,” he said.

“It’s not so much about the XV, it’s about the 30 there and – if injuries happen – the other guys coming in from the training squad who are really going to push on and excel.”

Among England’s attacking threats, Jonathan Joseph emerged from the Six Nations with the fastest-growing reputation.

With six international caps and no tries to his name at the turn of the year, Joseph crossed against Wales and Scotland, as well as grabbing a double against Italy.

The 23-year-old Bath centre now heads into the World Cup with control over the No.13 shirt – England golden boy Manu Tuilagi’s favoured position – and Robshaw admits that is no less than he deserves.

“He did well, didn’t he? He is a guy who has waited for his chance and grabbed it with both hands,” added Robshaw, who is an ambassador for the Lawson Keys National Rugby Awards at Twickenham on September 2.

“He is definitely one of those guys you want in your side, rather than against you, and a good guy to have around.”

Meanwhile, up front, Robshaw believes he is joined in the back row by another superstar in the making in the shape of 22-year-old Billy Vunipola.

The No.8 lost his place in the side to the impressive Ben Morgan during the autumn internationals but returned a new man after the new year, playing every minute of the Six Nations and joining Joseph among the Player of the Championship nominees.

Robshaw says the Saracens powerhouse could have a big role to play in England’s World Cup bid.

“I thought he was England’s best player,” he said. “He was tremendous throughout the whole campaign and I’m pleased for him that he was given 80 minutes as well.

“It was the first time he was given that and Billy rewarded that faith and really excelled.”
