Republic of Ireland's hopes of qualifying for the World Cup were dealt a huge blow on Tuesday after a 1-0 defeat to 10-man Serbia at the Aviva Stadium
Martin O'Neill's side started the evening with the chance of going top of Group D with a victory but former Manchester City full-back Aleksandar Kolarov (55) scored the only goal of the game as Serbia, who finished the game with 10 men after Nikola Maksimovic's 68th-minute red card, secured a top-two finish
Serbia moved four points clear at the summit but for the hosts, who drop down to third in the group, defeat leaves them with a mountain to climb to reach next summer's tournament in Russia, especially after Wales' 2-0 victory in Moldova
O'Neill asked for a response from his side following their disappointing draw against Georgia at the weekend, and they thought they'd made the perfect start when Shane Duffy converted Robbie Brady's cross from close range but the celebrations were cut short by the offside flag
Backed by the home crowd, Republic of Ireland continued to threaten and they went close again in the 20th minute through Shane Long, whose long-range effort was tipped over the bar by Vladimir Stojkovic
Serbia eventually grew into the game and in the 33rd minute created their first clear-cut opening
 Dusan Tadic's pass released Filip Kostic and he pulled the ball back for Aleksandar Mitrovic, but the Newcastle striker's goal-bound effort was clawed away by Darren Randolph
It was the visitors who were celebrating the 55th minute when Kostic guided the ball perfectly on to the fast-arriving Kolarov's left boot and he thundered it off the underside of the crossbar, leaving Randolph helpless
Ireland needed a response and O'Neill brought on striker Daryll Murphy to replace Wes Hoolahan with 28 minutes remaining, and the new man made a swift impact
As he set off in pursuit of Brady's ball over the top, last man Maksimovic slipped and was adjudged to have brought him down, prompting referee Cuneyt Cakir to brandish a red card, although Brady wastefully drilled the resulting free-kick into the defensive wall
Murphy was convinced he should have been awarded a 76th-minute penalty for a challenge by Jagos Vukovic as he tried to meet substitute Callum O'Dowda's teasing cross, and saw an 86th-minute snapshot palmed away by Stojkovic as the Republic's World Cup dream started to ebb away
Republic of Ireland looked a threat at set pieces all game but Stojkovic stood up to the challenge, commanding his penalty area to great effect
He also read the play brilliantly and showed excellent handling all night
He also made what proved to be a crucial save in the 86th minute to deny Murphy, sticking his right boot out to block the substitute's snapshot
Republic of Ireland, who will be without Robbie Brady and James McClean through suspension, face Moldova at home on Friday, October 6, before finishing their campaign on October 9 with what could be a decisive trip to Cardiff to face Wales
For Serbia, they can clinch qualification to the World Cup with victory in Austria on October 6 but should they need another game they face Georgia at home three days later
