Ireland v Argentina: Jonny Sexton urges players to win crucial game against Pumas for Declan Kidney Victory against the Pumas would at least guarantee Ireland a top-eight IRB seeding for the World Cup draw next month. However, depending on other results, a defeat could demote them to ninth and lead to renewed calls for Kidney's departure, not least because Ireland have scored only two tries in those five games. "We're all in it together and we've been on a poor run but they've done everything right by us, they work incredibly hard," Sexton, having been declared fit after a groin strain, said of the coaching staff. We will try to get the win that they deserve and that we probably deserve. Kidney had made one change from the team who lost 16-12 to South Africa two weeks ago, introducing Ulster's Craig Gilroy, who scored a hat-trick in the non-capped international against Fiji last week, on the wing instead of Andrew Trimble.
