While Ireland and France go head-to-head on Sunday, there's another pivotal Rugby World Cup pool clash this weekend.
With England eliminated, Wales and Australia vie for top spot in Pool A and the carrot of a potentially attractive route towards the semi-finals.
Wales great Shane Williams joined Off The Ball and guest presenter Brian O'Driscoll on tonight's show and Williams highlighted the Welsh confidence at present among the current crop of players.
"What you see now with Wales is that they just don't give up," he said, referencing the victory over England, but expects an aerial bombardment from Australia tomorrow.
Brian also gave his take on his former Leinster coach Michael Cheika and the way in which he has improved the Wallabies, while he also added: "For me, Australia has always been the smartest team in world rugby, irrespective of what personnel were there. They were always able to pull teams apart."
And don't forget Brian will be joined by Keith Wood, Felipe Contepomi and many more guests at Dublin's 3 Arena for our massive Off The Ball Roadshow on Wednesday.
