Full-time: Republic of Ireland 5-0 Northern Ireland
90mins: The ref blows it up on 90 minutes. Two wins for two now for the home side, who will play Scotland next on Sunday in what will probably be the decider.
88mins: Lawrence wins a free kick 25 yards out and Hunt hits the post with an excellent dead ball effort, the Waterford man was unlucky not to make it six.
84mins: Lawrence fancies a go now but his speculative effort is easily saved by Blayney.
GOAL: A smart ball from Treacy finds Cox who drifts to the edge of the North's box and finds an angle to shoot low and true into the bottom right corner from his left foot - a lovely debut goal for the West Brom man.
80mins: GOAL! Cox.
76mins: Republic retaining posession easily now against the ten men of the north - Ward eventually crosses well but the linesman flags for offside just as Hunt looked like he might reach it in front of goal.
73mins: Warren Feeney makes way for Liam Boyce, while Celtic's Niall McGinn also comes on for the North.
72mins: Stephen Hunt comes on for Kevin Foley in another change for the Republic, while David Forde replaces Shay Given in goal.
68mins: Foley, Lawrence and Cox combine well but Lawrence strays offside when just about to cross.
62mins: Keane is next taken off with Andy Keogh taking his place - Keane is clearly unhappy with the decision, obviously had a hat trick in mind. The tempo has gone out of the game following the expected substitutions though.
57mins: Substitutions as Coleman makes way for Lawrence. Gorman is replaced by Coates.
56mins: Keane goes close again, but this time his volley is excellently saved by Blayney.
GOAL (and sending off): Following a catalogue of errors from the North's defence, Keane ends up through on goal and is taken down clumsily by Thompson when about to shoot. Thompson, winning only his second cap, is red carded and Keane cooly slots his 48th international goal.
54mins: GOAL! Keane penalty.
Elsewhere, the Republic of Ireland have defeated Poland 1-0 in the UEFA Under-19 Championship elite stage Group 4 qualifier. Jeff Hendrick was Ireland's scorer.
50mins: The North begin the half with more purpose but despite retaining posession can find no use for it when in the last third.
46mins: Norwood comes on for McQuoid in the only half time change for the North as the second half begins.
HALF TIME: Republic of Ireland 3-0 Northern Ireland
GOAL: Keane, Cox and Coleman combine beautifully on the right of the Northern box and Coleman is free to cross from the end line on the edge of the six yard box. It's low and close to the goal line when Cathcart deflects it in - it's getting easier for the Republic.
45mins: GOAL Cathcart own goal.
44mins: Ward, looking assured coming forward from left back, puts in a lovely cross but Coleman can't quite reach it.
39mins: Moments later a Coleman shot is snuffed out by a sliding McAuley.
GOAL: Young Northern full-back Hodson makes a terrible mistake from left back as his short back pass is cut out by Keane in the box. Robbie clips it past Blayney into the top corner from an angle for his 47th international goal.
37mins: Goal! Keane.
34mins: Republic playing keep-ball at the moment, and very well too but Cathcart and McAuley are on hand for the North, with clearing headers when they do eventually get crosses into the box.
29mins: The Republic looking more and more comfortable as the game goes on. Cox and Keane already look to have an understanding in attack, while Treacy and Coleman are also looking lively.
GOAL: Treacy takes a quick short corner and delivers the return into the danger area but Blayney spills when he should have held on and Ward is on hand to score from close in for a debut goal.
24mins: GOAL! Stephen Ward.
21mins: Hodson and Gorman then combine well for the North down the left but the eventual cross is easily cleared by the Irish defence.
17mins: New boy Cox then makes a break into the box from the left and cuts it back to Andrews who sees his curler from the edge of the box come back off the post.
14mins: Andrews and Coleman coming into it now for the Republic as they manage to string a few passes together. Republic end up with a corner which is cleared but Coleman retrieves and puts in a good cross but McShane is flagged offside at the back post. Treacy then has a shot on target but it's straight at Blayney in the North's goal.
9mins: Neither team has settled yet, although the North look the brighter early on.
2mins: Early chance for the North when a poor clearance from a free in falls to Gorman on the edge of the box and his volley flashes past the upright.
19:45pm: And we're off. Northern Ireland get the game underway with the sun still shining.
19:41pm: The teams line up for the national anthems - both anthems are booed by the opposing set of supporters, although not very loudly because there's very few in attendance tonight.
19.30pm: Stephen Ward starts in defence in place of Mark Wilson for the Republic in a change from the originally named starting XI.
19.17pm: It's a bright breezy evening in Dublin as the two Irelands prepare for their second game in the Carling Nations Cup. Back in February the North lost their first 3-0 to Scotland, while the Republic defeated Wales by the same scoreline.
