16:40 GMT 21 March 2015So England need a 26-point winning margin over France to bag up the Six Nations title.
What does history tell us?
Well, England have only managed to rack up that scale of victory against France on three occasions in Five/Six Nations history.
Two of those wins were way back when - 37-0 in 1911 and 39-13 in 1914 - but Stuart Lancaster's men may take heart from the 48-19 drubbing dished out at Twickenham in 2001.
It was the day that Jonny Wilkinson became England's all-time highest point-scorer by the way.

16:39 GMT 21 March 2015What? You want more drama? Good thing we've got Le Crunch to round things off then - kick-off is less than half an hour away.
A recap of the day so far.
First, Wales annihilated Italy in Rome to set a seemingly impossible points difference for Ireland and England to overhaul.
But lo and behold, defending champions Ireland then battered Scotland in Edinburgh to take their points difference out to +63.
And now England will try to beat France by 26 points or more to take the title - otherwise Ireland will be champions once again

Allison: I'm a US citizen with Scots, Irish and English in the family tree, but married into a Welsh family - so Cymru am byth it is!

16:27 GMT 21 March 2015BBC Sport's Andy Burke at Murrayfield: "Thousands of Irish fans stay behind here at Murrayfield to hail their conquering heroes. They simply blasted Scotland away in that second half.
"We'll see if it is enough to retain their Six Nations crown, but one suspects those who've travelled across the Irish sea will enjoy their evening in Edinburgh whatever the outcome..."

"We've our post-match meal now and will dine with the Scotland team. It will be a nervous afternoon."

16:22 GMT 21 March 2015Thomas Maxwell: Incredible from Ireland. Whatever England do, that's gone a long way towards redeeming last week.
James Latham: Shambolic home performance from Scotland. Not sure they deserve their place in the Six Nations.
Mike: Can we replace Scotland with a more competitive team in next year's Six Nations? How about Romania?

16:21 GMT 21 March 2015Stewart Nisbet: Please stop deluding yourselves by saying Scotland are making progress - they're not. This is the worst Scotland side seen for years, incapable of executing the basics and no heart. Apologies to Wales, we have simply rolled over to the Irish. Pathetic and frustrating in equal measure. The table doesn't lie, Scotland are the worst side in Europe. The much vaunted Vern Cotter needs to show what all the hype is about.

16:21 GMT 21 March 2015Ireland's two-try scorer Sean O'Brien on BBC One: "We knew what we had to do at half-time and we executed it very well.
"It was important we expressed ourselves. We had to win the game first and foremost and we stuck to our guns and got the result.
"We're going to wait very anxiously. Our eyes will be glued to the England game."

16:21 GMT 21 March 2015What that performance from Ireland shows is that Joe Schmidt's side can play more than one way - they've got different tools for different jobs and will surely be a threat at this year's World Cup.
Scotland, alas, were as poor as I've seen them for some time. They've won one of their last 12 Six Nations matches, have won the wooden spoon again and will surely be no threat to anyone at this year's World Cup.
