ITALY v IRELAND
FORM
Ireland have scored 45 tries across their last seven games against Italy in the Six Nations (6.4 per game), scoring eight or more tries in three of their last five clashes.
Italy have conceded a try-scoring bonus point in 17 of their 22 matches since those incentives were introduced to the Six Nations in 2017; only England (9) have picked up more bonus points in the championship than Ireland (8). The Azzurri are the only side yet to register one.
Ireland have lost their opening two games of a Six Nations campaign for the first time. The last time they lost their opening three matches was in 1998, when they were beaten in all four Five Nations clashes.
ONES TO WATCH
Sebastian Negri has made 96 metres and made 21 tackles combined in Italy's losses to France and England. Franco Smith will need another strong showing from the flanker.
Ireland back-row CJ Stander has made more carries (36) than any other player in the 2021 Six Nations. He has topped the final rankings for this category in three of the last four editions of the championship.
WALES v ENGLAND
FORM
England have won six of their last seven Six Nations matches against Wales, with the last six of those fixtures all decided by a single-figure margin.
Wales have won their opening two games of the tournament for a sixth time. On four of the previous five occasions when they have started with back-to-back victories, they have gone on to win a Grand Slam (2005, 2008, 2012, 2019, not in 2009).
This weekend's visitors are the only team to have never conceded more than two tries in a Six Nations game played in Wales. They have scored 19 tries in Wales during the Six Nations, no visiting team have scored more (Ireland also 19).
ONES TO WATCH
North will become only the sixth Wales player to win a century of caps. The 28-year-old will form a new pairing with Jonathan Davies and will be looking to bring up his hundred with an all-action display.
Elliot Daly will win his 50th cap for England and coach Eddie Jones will expect the full-back to repay the faith he has shown in him after a slow start to the tournament.
