Ireland's Six Nations campaign is back up and running after their stunning win in England last time out.
This week Wales are the visitors to Dublin looking to end a 14-game losing streak in the championship.
Andy Farrell's men have an outside shot at the title but need France to slip up against Scotland or England, while a Triple Crown is very much on the cards.

WHAT THEY SAID
Andy Farrell (Ireland head coach): "It's been written many times about the decline and how unfortunate it’s been but, from what I’ve seen, they’ve got better every week. They’re coming to Dublin with a spring in their step. Those lads want to right a few wrongs and be part of the squad that turns Welsh rugby around. That makes them dangerous."
Steve Tandy (Wales head coach): "It's about backing up from the performance against Scotland. Obviously, it’s a different context. Going away from home, is a different type of environment for our group, but the focus for us is really improving on what we did last [match]."
