The Irish provinces kick off their European campaigns this Saturday, facing tough competition from France, Italy, and England. In the Investec Champions Cup, last year’s finalists Leinster head to France to clash with Clermont Auvergne at 15:15 BST. Meanwhile, Connacht hosts Saracens at 17:30 and Munster welcomes Racing 92 to Cork for an evening match at 20:00.

Ulster also begins their journey in the Challenge Cup, taking on Zebre at 15:15. Richie Murphy’s side aims to avenge last season’s final loss to Montpellier.

In Leinster's lineup, Joey Carbery makes his first appearance in eight years, coming off the bench. The starting XV boasts 14 Ireland internationals, with Dan Sheehan captaining in Caelan Doris’ absence. Key players include:

• Andrew Porter and Tadhg Furlong in the front row
• Joe McCarthy and James Ryan in the second row
• Ryan Baird, Josh van der Flier, and Jack Conan in the back row.

Munster, marking the 10-year anniversary of Anthony Foley’s passing, makes six changes from last week’s URC draw. Four players will debut in the Champions Cup, including Charlie O'Shea and Sean Edogbo. The match will also see the number eight jersey retired for the day.

Ulster’s squad features new faces, including Daniel Hawkshaw making his debut alongside Jake Flannery in midfield. David McCann assumes captaincy of a youthful side missing several key players due to injury.

As the Irish provinces prepare for these crucial matches, fans eagerly await an exciting day of European rugby.
