As we've seen during this year’s competition, the RBS 6 Nations has a habit of serving up great drama.

Theatre is one thing but good old-fashioned rivalry is another - when England lock horns with Scotland this weekend, two of rugby's oldest adversaries will be determined to restore some pride to their wounded nations.

Both teams have had to endure two difficult weeks of reflection in the wake of defeats during their last outings.

Whilst England were given a lesson in ruthlessness by a clinical Irish performance at Twickenham, Scotland were humbled by a determined Italian side, who secured only their ninth RBS 6 Nations victory since they first took part in the competition back in 2000.

It's often a bad idea to underestimate a wounded animal. England and Scotland will be hurting but both will want to leave their stamp on Murrayfield, biting back at the first available opportunity.

Winning on Saturday is vital for both teams however Martin Johnson and Andy Robinson have very different agendas in the context of the championship.

Whilst England are still capable of topping the overall standings, Scotland are facing the very real prospect of taking home the wooden spoon.

The Scots have two games to save themselves but it doesn't look good.

If Scotland need any extra motivation to topple England in front of their home fans, they need look no further than head coach Andy Robinson.

Andy had a tricky time of things when he was in charge of England and the media didn't help matters, heaping pressure on the team week after week.

If anyone in Murrayfield has a point to prove come Saturday it is Andy.

What better way to silence the critics than to put one over your fiercest rivals?

Delon Armitage has shaken off the rib injury sustained during the defeat to Ireland which means England's backline remains unchanged.

Ben Foden, who was widely tipped to get his chance to impress from the start, will have to settle for a place on the bench.

Various members of England's pack have been involved in off-field issues since the last game and it will be interesting to see how they react against Scotland.

The first was James Haskell who found himself, somewhat unfortunately, right in the middle of a club versus country row and has been quick to admit that it has been an awkward time for himself.

He'll be happy to concentrate on playing once again.

Another player making headlines recently is Lewis Moody.

Arguably England's best player over the last 12 months, Lewis announced that he is to move on from Leicester, after 14 years at Welford Road, to join Bath at the end of the season.

A surprising move made even more so by the fact that it seems to have cost him his place in the starting lineup.

The ever reliable Joe Worsley comes in for his 73rd cap but the decision to drop Moody is a strange one.

For Scotland to be in with a chance of winning, much will rest on the broad shoulders of their British & Irish Lion Euan Murray.

Murray, who made his international debut against England at Twickenham in 2007, is one of the form players in the premiership and the Scots will need him to bring his big game experience to the fray.

In the backs, Sean Lamont has proven his quality in both attack and defence.

Whether he can produce the level of rugby required on a consistent basis remains to be seen but he had decent games against both France and Wales and will be looking to put in another mature performance against England on Saturday.

By the time the game gets underway the Dallaglio Cycle Slam will have reached its conclusion.

In total I’ve cycled 2,800km, with the help of some dedicated friends, from Rome to Murrayfield, taking in Paris, Twickenham, Cardiff and Dublin along the way.

It was a crazy idea at the outset I know, however it’s all been in aid of Sport Relief and the Dallaglio Foundation making the physical challenge well worth it.

To relive parts of the ride or to make a donation please visit www.dallagliocycleslam.com If England are to keep alive their aspirations of being crowned champions in Paris on 20 March they cannot afford to slip up.

Scotland are in a fight all of their own and the fact that both teams are desperate to win, albeit for entirely different reasons, could make for an explosive encounter.
