Munster breakthrough next on the agenda for O’Sullivan

One day you’re the breakout star of the U20 Six Nations. The next you’re fighting to keep your favourite No. 8 jersey for the World Cup.

That’s Jack O’Sullivan’s dubious reward — and Ireland coach Noel McNamara’s joyful headache — as Ireland’s preparations for the U20 World Cup are set to step up a notch.

Ireland will travel to England next month with the pick of the No. 8s from the last two Six Nations, two-time man-of-the-match O’Sullivan and highly-rated Leinster prospect Caelan Doris, who starred alongside Jordan Larmour in 2017 but missed this year’s campaign through injury.
