England will hurl themselves into Saturday's RBS Six Nations title decider against Wales under the roof of the Millennium Stadium believing they are ready to end their decade-long wait for a Grand Slam.

Forwards coach Graham Rowntree said: 'I look at how we have improved over the last year and I think it's the right time for us.

'The signs are that this group of players is ready. It's been 10 years and it took four years to win that Slam. We have to understand that, but I think we're ready.'

The teams agreed that the stadium roof will be shut to keep out the forecast wet weather, a move that will further intensify the electric atmosphere.

But England are alive to the danger of being distracted by pre-match interruptions.

Captain Chris Robshaw said: 'We've prepared for a marching band coming through our warm-up and disrupting things. You can't let that get to you.

'We experienced it in Scotland last year - they had a pipe band which suddenly appeared as our coach arrived and did an extremely slow walk which delayed us by 10-15 minutes.'

After Lancaster targeted a Slam as a stepping stone to the home World Cup in 2015, Wales assistant coach Robin McBryde said: 'Perhaps England are getting ahead of themselves a bit, though it is obvious they have a good foundation to build on.

RBS 6 NATIONS TITLE - PERMUTATIONS

England's victory over Italy means a win against Wales in Cardiff would seal a first Grand Slam in a decade.

However, Wales have everything to play for because a victory for them could be enough to retain the RBS 6 Nations title and leave England empty-handed.

England are currently two points ahead of Wales in the table and with a points-difference advantage of 14.

Under tournament rules, if the points and points difference end level then the championship would be decided on tries scored.

Wales hold the advantage 7-5 going into the final round. If tries scored is also level, the title is shared.

Here, we examine the permutations:

ENGLAND WIN GRAND SLAM

An England victory by any margin would secure a first Grand Slam triumph in a decade.

ENGLAND WIN TITLE

An England defeat by six points or fewer would still be enough to seal the title.

If England lose by seven points but outscore Wales by three tries or more then Stuart Lancaster's men would win the title.

WALES WIN TITLE

A Wales victory by seven points, providing they stay ahead of England on tournament tries, would see Rob Howley's men retain the title.

TITLE SHARED

If Wales win by seven points but England score two more tries then the title would be shared.
