France and Ireland face off at the Stade de France on Saturday in a contest that may well determine exactly where the Six Nations title ends up next month.
Pre-tournament favourites France kicked off their campaign with a routine victory over Italy, while a much-fancied Ireland proved far too strong for reigning champions Wales.
Both sides picked up bonus points to lead the way at the top, setting up a mouth-watering encounter in the French capital as Ireland aim to stretch their nine-match winning run.
Wales have a chance to respond to last week's disappointment when they host a Scotland side who should be full of confidence following their Calcutta Cup win over England last time out.
The final match of the weekend takes place in Rome as perennial whipping boys Italy take on England with the aim of ending their long-running losing streak in the competition.

WALES v SCOTLAND
FORM
Wales have lost just two of their 11 home matches against Scotland in the Six Nations, though one of those losses did come in the last such meeting two years ago at Parc y Scarlets in Llanelli.
The last three encounters between the sides in the competition have been decided by a margin of seven points or fewer. Indeed, four of the last six clashes have seen the side losing at half-time come back to win the match.
Scotland are on their longest away winning streak in the championship, having won four on the spin – not since between 1925 and 1927 have they won five in a row on their travels. However, Wales have won nine of their last 11 Six Nations home matches.
ONES TO WATCH
Taine Basham was a rare shining light for Wales in their heavy loss to Ireland, the tournament debutant crossing over late on to prevent his side from losing to nil on a day to forget in Dublin. Basham also made 22 tackles, which is the most of any player on the opening weekend, missing none in the process.
A number of Scotland players impressed in the late win over England, not least Darcy Graham. The diminutive wing set up Ben White for the opening try, won the crucial turnover in injury time and beat six defenders – the most of any player in round one.
FRANCE v IRELAND
FORM
France and Ireland have played each other 100 times previously, with France victorious on 58 occasions, Ireland prevailing 35 times and seven games drawn. In the Six Nations, Les Blues edge the win record 11 to nine from their 22 previous encounters, the other two matches finishing level.
Ireland have lost their last two meetings with France in the competition, having been beaten in just one of the previous eight. Ireland's win rate of 41 per cent against Les Blues in the Six Nations is their lowest against any side.
After recovering to see off Italy last week, France are aiming to win their opening two Six Nations games for the third year in a row, this after managing it just twice in their previous eight campaigns.
ONES TO WATCH
France head coach Fabien Galthie, back involved after missing the Italy match with coronavirus, has put his faith in youth by handing Yoram Moefana his first Six Nations start. The 21-year-old impressed in his cameo role against Italy by playing a part in his side's last two tries.
Ireland will have to make do without injured skipper Johnny Sexton, who passed the 500-point mark in the Six Nations last week, so all eyes will be on Joey Carbery – the only change from the Wales game – at fly-half. The Munster number 10 is tasked with pulling the strings on his first tournament start.
ITALY v ENGLAND
FORM
England are the only side Italy have never managed to beat in the Six Nations, losing all 22 of their previous showdowns. England's 80-23 win in this fixture 21 years ago remains the most points scored and biggest winning margin in any fixture in the competition's history.
Italy have lost their last 33 matches in the competition – the longest losing streak by any team in the Five or Six Nations – in an unwanted run that stretches back to a win over Scotland in 2015.
Eddie Jones' visitors have lost their last two Six Nations matches, but only once over the last 15 editions have they lost three in a row, while not since 2005 have they lost their opening two games to a campaign.
ONES TO WATCH
Italy's Michele Lamaro (21 tackles) was one of just three players to make 20 or more tackles during the opening weekend, along with Basham (22) and Nick Tompkins (21). However, he also missed four tackles, which was the joint-most of any player, level with Dan Biggar.
Ben Youngs, who made the most kicks in play of any player in round one (17), is one of six players to make way for England. Should the experienced scrum-half make it off the bench, he will become England's joint-most capped player of all time alongside Jason Leonard with 114.
