A look at every team competing in the 2019 Six Nations championship, as Ireland look to follow up their Grand Slam triumph.
The 2019 Six Nations gets under way on Friday, when France host Wales in Paris.
Ireland won the Grand Slam last time around and begin their campaign in Dublin on Saturday against England, whose Twickenham home was the setting for the defending champions' crowning moment in 2018.
Scotland will be keen to continue the improvements of recent seasons, while for Italy the priority will be ending a Six Nations losing run which stands at 17 matches.
Here we take a look at the teams and what each can expect from their 2019 campaign.
Who's in charge?
Joe Schmidt is nearing the end of his time at the Irish helm after announcing that he will leave the job at the end of the World Cup. Successor Andy Farrell is already on Schmidt's staff and will be taking notes during this year’s championship.
Rory Best has skippered Ireland for the past two years – a period of tremendous success for Schmidt’s side that has seen them crowned Grand Slam winners and beat the All Blacks for the first two times in their history. He is the oldest player in this year's championship at 36.
Who's the key man?
Ireland boast World Rugby's Player in the Year in the shape of fly-half Johnny Sexton. He has faced a race to be fit for the opener against England but will be key to Ireland's success if he has shaken off the effects of a knee injury. Wing Jacob Stockdale - player of the tournament in 2018 - also poses a threat to any defence.
What happened last year?
Ireland completed the Grand Slam at Twickenham on the final weekend of the championship, consigning their opponents to a fifth-place finish. It was Ireland's first clean sweep since 2009.
What's expected this year?
Ireland have arguably enhanced their reputation since last year’s championship, picking up a series win in Australia, as well as a 16-9 victory over the All Blacks in November. If they can keep up that kind of form over the coming weeks, they will prove themselves to be serious contenders for the 2019 World Cup.
