On Saturday night we will finally find out who are the Guinness Six Nations champions for 2019.
Three fascinating fixtures will take place on Super Saturday and, with everything still to play for, our partners AWS have done some digging to find out where each game could be won and lost.
We start in Rome where the Azzurri are looking to end their Championship on a high with their first victory of 2019.
They have history on their side, in 2011 and again in 2013 they beat France in the Italian capital and also gave Les Bleus a real fright three years later in Paris.
One of the key areas in the Stadio Olimpico clash will be the final quarter.
Jacques Brunel’s side have impressed in the last 20 minutes of games, most recently against Ireland in Round Four.
29 of their 68 points this Championship – 42.6% – have come in the final quarter while the Azzurri have conceded 42 points in that quarter, more than any other side.
But France will need to beware the Italian lineout which rules the skies in the Championship with a 95.1% success rate on their own ball and nine other lineout steals.
Conor O’Shea’s side will also need to scramble well, France have made the most linebreaks in this year’s Championship and Yoann Huget leads the way individually with six.
On top of that, they also have the three best offloaders in the game in the form of Antoine Dupont, Mathieu Bastareaud and Louis Picamoles.
But the Italian defence has looked strong at times in this year’s Championship – Ian McKinley and Alessandro Zanni are both yet to miss a tackle this year and the former could be named in midfield on Saturday to combat the French threats.
Discipline will also be key, both Italy and France are the two most penalised sides this year and Demba Bamba in particular will need to tidy up after being pinged six times already.
Keep an eye out for Abraham Steyn as well, the Italian flanker is one of only two men – the other is Billy Vunipola – to have broken the half century for carries this year.
France’s 92% tackle success rate as a team will surely be put to the test on Saturday in Rome, both sides come into the game with nine tries scored and we should expect a few more in this their Championship finale.
Wales have history on their mind in Cardiff while Ireland are looking to spoil the party and defend their own Championship crown.
Never before has one head coach won three Grand Slams in the Six Nations era but Warren Gatland is 80 minutes away from the feat in this, his final year at the helm.
Wales have won the last two times Ireland have come to Cardiff but Ireland hold the overall edge in their meetings this century with 11 wins from the 19 meetings.
It is shaping up to be a battle of Ireland’s attack against Wales’ defence.
Ireland top the possession charts in the Championship at 57.1% but Wales have shipped a Championship-low six tries across the first four games.
As well as all their ball, Ireland also generate the quickest recycling at ruck time with an average of 3.21 seconds.
That efficiency will be sorely tested this weekend however against a Welsh team that slow ball better than anyone else in what has become a calling card of their 13-match winning run.
If Wales are to win, you would think their lineout will need to function better than it has been.
Their Championship success rate of only 74.4% is the worst of the six teams while Ireland have made their lineout their key attacking weapon.
Eight of Ireland’s 13 tries originated from lineout ball and Shaun Edwards will surely be paying close attention there.
Watch out for the period just after half time as well, Ireland are yet to concede a single point between 40 and 60 minutes in any of their games so far this year.
But something has to give, because Wales have scored 27 points in that window after half time, more than any other side.
Individually speaking the key men might well be the wings.
Only Blair Kinghorn has made more metres than Jacob Stockdale’s 406m across the first four games, the Ulsterman also has a Championship-high six tackle breaks to go with it.
However, Stockdale has also turned the ball over nine times, more than anyone else, and in Josh Adams is facing off against a man with three tries in his last three games and who carries further than any other Welshman.
Ireland’s key man however remains Peter O’Mahony. The Munster star has accounted for all four of Ireland’s breakdown turnovers this year and also has claimed 23 lineouts – both are the highest in the Championship typifying his dual threat on the ground and in the air.
Should Ireland do them a favour in Cardiff, England will take on Scotland knowing that the Championship is theirs for the taking.
Scotland have not won at Twickenham since 1983 but are the Calcutta Cup holders after last year’s famous triumph.
The numbers make for interesting – and contrasting – reading here with two opposing styles facing off.
England kick the ball away more than other side – 134 from hand this Championship compared Scotland’s 82.
As a result, Scotland can expect plenty of possession on Saturday while England are happier without it – their total of 43.2% possession is the lowest of all six sides despite their 19 tries and counting.
Scotland are used to carrying a heavy load, they lead the way with 3629m so far this year while England are the tackle kings with over 1,000 already – and despite their defensive load have only shipped seven tries.
If Scotland are to have any chance, they will need to start well at Rugby HQ.
England have come storming out of the blocks, and their 88 first-half points are more than Scotland’s overall total of 67.
From an English point of view, Owen Farrell’s 48 points are the most in the Championship while Jonny May is out in front on the try-scoring list with five.
But Scotland have plenty of threats as well, Jamie Ritchie is a breakdown nuisance with four turnovers already while Hamish Watson’s destructive carrying is sure to test this much-vaunted English defence.
But the real key could come down to discipline where England have been whiter than white.
Their total of only 24 penalties conceded is comfortably the best in the Championship while Scotland on 37 are the worst.
If Scotland don’t clean their act up, then England will turn the screw and with a 99.1% success rate on their own rucks, it could be a while before Scotland get the ball back.
