Munster will finally get to unleash summer signing Diarmuid Kilgallen at Northampton Saints on Saturday, one of three new faces for the Champions Cup pool decider alongside Peter O’Mahony and Diarmuid Barron.

Kilgallen, 24, has been restricted to just one appearance since his arrival from Connacht in pre-season, but made a big impression on the wing against the All Blacks XV on November 2 having recovered from a leg issue.
