Ross Moriarty went from villain to hero for Wales as Warren Gatland's team beat 14-man France 20-19 to reach the Rugby World Cup semi-finals.

His 74th-minute try shattered the hopes of a France side who had looked like clinging on for victory after Sebastien Vahaamahina saw red for a disgraceful elbow into the face of Wales flanker Aaron Wainwright.

France scored a pair of tries inside the opening eight minutes and led 19-10 at half-time, with replacement Moriarty having spent a costly 10 minutes in the sin bin.

But Vahaamahina's moment of recklessness proved pivotal, with Wales eventually making their extra man count in a nail-biter - just as France did when beating the Red Dragons 9-8 in the 2011 semi-final at Eden Park.
