Hugo Keenan knows all about how Irish dreams can die in Cardiff but says Peter O'Mahony's red card in the 2021 loss is being used as "extra fuel" to end a losing cycle.
He was 19 when he travelled to the Welsh capital in 2015 for a dream double as a rugby supporter - he had tickets for the World Cup quarter-finals between France v New Zealand and, the following day, for Ireland v Argentina.
But hopes turned to dust against the Pumas and so Keenan was there to witness Ireland's collapse in the last eight and, at that time, playing in green was not in any way on his horizon.
