Champions Cup: Will Connors tasked with keeping Billy Vunipola in check on debut

Openside flanker Connors is one of four changes to the side which beat Ulster 27-5 in last Saturday’s PRO14 final

Will Connors of Leinster and Billy Vunipola of Saracens

Will Connors will embark on his European debut today as a man on a mission, charged by Leo Cullen with shutting down Billy Vunipola and his fellow Saracens big ball-carriers.

Connors is one of two Heineken Champions Cup rookies in the Leinster starting line-up for their pivotal quarter-final clash with the defending champions. Fellow 24-year-old Hugo Keenan has retained his place on the right wing to make his competition bow at Aviva Stadium while lock Ryan Baird, 21, could also earn a European debut off the bench.
