England begin their home World Cup campaign against a dangerous opponent in Fiji tonight, here are five things to watch out for on the opening night of the Rugby World Cup.

1 – Norfolk boys in the thick of the action

Norfolk-born brothers Ben and Tom Youngs are in the England staring XV for the tournament curtain-raiser, with Ben winning his 50th cap.

In normal circumstances Ben would be given the honour of leading the team out to mark the occasion but on a night of such huge importance, captain Chris Robshaw retains that honour.

Ben, 26, instead led the team out for the traditional Captain's Run training session at Twickenham yesterday but the scrum-half will still have a vital role to play.

2 – Focus on the set-piece

The match will also be hugely important for Tom Youngs, as the hooker has come in for criticism from some for his skills at the lineout and scrum.

The 28-year-old former Holt and North Walsham player will be looking to prove his experience in both situations against Fiji, so that he can push forward as England's first-choice No2 throughout the rest of the tournament.

As a former British & Irish Lion and Aviva Premiership Player of the Year with Leicester Tigers, Tom should be fired up to prove his case.

England's scrum improved in the final warm-up victory over Ireland but forwards coach Graham Rowntree will be looking for much more from the entire pack now that the big moment has arrived.

3 – Beware the opponents

England are unlikely to get an easy ride in their opening match, even with the added energy of 82,000 supporters behind them at HQ.

Fiji are the reigning Pacific Nations Cup champions and are ranked ninth in the world, ahead of Scotland and Italy.

The likes of Leicester centre Niki Goneva, flying winger Nemani Nadolo and star scrum-half Nikola Matawalu – who joins Bath after the tournament – are all capable of big performances.

They are more than likely to score at least one try due to their flair and power but England's experience should allow them to keep that danger at arm's length.

4 – England's fire power

Fiji may have some exciting talent on show – but so do the hosts.

The flair and skill of Jonathan Joseph is balanced by the brutal defence of Brad Barritt at centre, with the big-hitting of converted rugby league star Sam Burgess in reserve on the bench.

The brilliant pace of wingers Jonny May and Anthony Watson, as well as world class full-back Mike Brown, mean their are high hopes that Stuart Lancaster's side will play some attractive rugby.

For those exciting skills to flourish however, the forwards must make sure to take control of the game up front early on.

5 – Enjoy the spectacle

All of tonight's action is being broadcast on terrestrial television, on ITV, as well as on the radio, with BBC Radio Five Live.

The opening ceremony pre-show begins at 6.45pm before the fanfare officially starts at 7pm, lasting 20 minutes before making way for the players to begin their warm-ups.

The England and Fiji players will be assigned an area to loosen up by the side of the pitch during the ceremony but will not have enough space to practice their set-pieces or kicking.

Kick-off for the match is then at 8pm – preceded, no doubt, by raucous renditions of the National Anthem and Swing Low, Sweet Chariot.
