The final game of Ireland's Pool A campaign looms this weekend as Joe Schmidt's side prepare for Somoa on Saturday. 
On this week's Balls.ie Rugby podcast, World In Union, the lads look ahead to this weekend's game and the team that should start. Will Ireland risk Garry Ringrose for the fourth game in a row this tournament? Who should play at full-back? What impact will the weather have? 
Elsewhere, we caught up with former Irish rugby player and current Connacht Sregenth and Conditioning coach Johnny O'Connor. He gives an expert insight into the inner workings of a professional rugby team and how programmes are tailored to players, specific positions and in-season load. 
Finally, there's some style chat and a look at the dreaded scenario; what happens if England win the World Cup?
