It’s a big weekend of rugby with all four Irish provinces in action in the Champions Cup and Challenge cup.

Connacht host Bayonne tomorrow at 17:00 in the Challenge cup, having won their opening games, while at 17:30 Munster face Clermont in the Champions Cup. Just like Connach,t the Reds have won their opening two games but the top-14 side will represent a huge step up in class.

Late on Satutday evening, Ulster host Scarlets in Kingspan Park, needing a win with a bonus point to have any chance of keeping their European season on track. On Sunday, a two-for-two Leinster face Harlequins at the Twickenham Stoop - a game you can hear live and exclusive on Off the Ball.

Former Heineken Cup winner with Leinster and current Grenoble coach Bernard Jackman joined us on Newstalk Breakfast to discuss the weekend’s action:
