Simon does not want the game to be about him, but the players will want to finish with a bang and send Simon off in the right way.

This is what it's all about.

Anna, 13, is here with her dad Adam. She started playing rugby a couple of years ago after watching the Red Roses on TV.

They've never been to a women's match before but are loving the atmosphere around Twickenham.

Adam has been to men's games here before and pointed out the advantage of tickets for this one being so much cheaper at around £20-30 for adults and £5 for children.

He says there is a noticeably different vibe as well, with around 50% of the tickets today being bought by women.

Gaelle Hermet may no longer be France's captain, with Audrey Forlani taking that role for the tournament, but she is still a leader for Les Bleues, as Marlie Packer is for England.

Packer herself described Hermet's performance against Wales as "massive".

The England captain's return to fitness after sustaining an ankle injury in last weekend's match against Ireland is a massive boost for the Red Roses.

The flankers will face off at the breakdown, which will likely be a key battleground as both sides attempt to stop the other from getting quick ball to fuel their rapid backlines.

Packer has won five turnovers in the tournament so far and Hermet four. The England captain is the tournament's top try-scorer with six.

As well as being motivational presences in the pack, both players are equally capable of a break down the wing more characteristic of a back-three player.

Fly-half Holly Aitchison facing Jessy Tremouliere is a case of the student against the master.

Tremouliere, 30, is a legend of the game and former World Rugby player of the year winner. She will retire from international rugby after Saturday's match.

Aitchison, 25, took the reins at 10 at the start of the Six Nations because England's usual starting fly-half, Zoe Harrison, is missing the tournament with a torn anterior cruciate ligament.

Aitchison has blossomed, taking charge of England's improving attack and distributing the ball to her talented back three.

Tremouliere may have more experience of big occasions to prepare her for the Twickenham crowd, but both have played sevens at the Olympics and neither is afraid of a creative cross-field kick.

England captain Marlie Packer says of the France 10-12 combination of Tremouliere and Vernier: "We need to make sure we shut that down early."

Inside centre Gabrielle Vernier has been one of France's top performers this tournament, becoming a key cog in an increasingly exciting attacking structure.

Conversely, England's Helena Rowland is making her first start of the year at outside centre - an unfamiliar position.

Rowland was a reliable and smart full-back for England at the World Cup last year but missed out on the final defeat because of a foot and ankle injury sustained in the semi-final.

The 23-year-old will also take on goal-kicking duties on Saturday - an area in which England have struggled this tournament.

Despite that lack of game-time, England head coach Simon Middleton says Rowland is "definitely the right call", adding that she had played 13 "an awful lot in training".

"Sometimes you roll the dice a bit and see what comes up," Middleton said.

"I think Helena is such an adaptable player, such a talented player. She just gives us a different dimension."

Victory for either side today may come down to individual brilliance.

Let's take a look at three of the key match-ups to look out for...

England captain Marlie Packer sustained an ankle sprain against Ireland last weekend, but she's starting today all the same.

Packer will run out with two-year-old son Oliver before today's match. He helped out with her warm-up, toddling off down the tunnel and forcing Packer to give chase.

He's hanging out on the touchlines now, so was obviously retrieved.

In case you missed the team news this week, this is how both sides will line up...

England: Kildunne; Dow, Rowland, Heard, MacDonald; Aitchison, L Packer; Botterman, Davies, Bern; Aldcroft, Beckett; Kabeya, M Packer (capt), Matthews.

Replacements: Powell, Carson, Muir, Cleall, Talling, Hunt, Reed, Breach.

France: Boulard; Banet, M Menager, Vernier, Llorens; Tremouliere, Bourdon; Brosseau, Sochat, Bernadou, Feleu, Forlani (capt), Berthoumieu, Hermet, Escudero.

Replacements: Riffonneau, Mwayembe, Khalfaoui, R Menager, Gros, Chambon, Arbez, Filopon.

Now then, here's a little something to whet the appetite before the action begins...

The magnitude of Saturday's Women's Six Nations Grand Slam decider is so great that even England head coach Simon Middleton admits to being nervous.

The Twickenham tapestry has been woven with many storylines.

The largest women's rugby crowd in history awaits. England can ease World Cup heartbreak. France look to heal a five-year-old wound. Middleton hopes to sign off an eight-year project in the right way.

It is a good job the Sugababes are booked for half-time to diffuse some of the tension.

After relatively straightforward tournaments so far, a much tighter scoreline will be seen in front of an expected record crowd of more than 53,000.
