A superb James McClean goal in the 57th minute gave Ireland the victory they required against Wales.
Some determined play from Jeff Hendrick down the right wing - which saw the ball somehow stay in play - found the Ireland midfielder in space near the corner flag.
Hendrick sent a low cross in the direction of Harry Arter. Rather than take control, Arter brilliantly dummied allowing the ball to find its way to James McClean near the penalty spot.
As he's done throughout this World Cup qualifying campaign, McClean scored another crucial goal for Martin O'Neill's side.
It was McClean's 10th goal for Ireland.
James McClean, you absolute dancer. How about that step over from Harry Arter?!? #WALIRL #RTEsoccer pic.twitter.com/75hDzigE9L
