Stand-in Ireland captain Peter O’Mahony says it is refreshing to see “hugely ambitious” Jack Crowley’s fearless approach to international rugby.

Crowley was handed his maiden Test start at the 11th hour for Saturday’s nervy 13-10 win over Australia after influential skipper Johnny Sexton suffered a calf injury ahead of kick-off.
