Group D's top two meet at the Aviva Stadium on Tuesday and Ireland will be looking to make amends with a home win after dropping two points in Tbilisi. Each time a Shane Duffy header or a Glenn Whelan hoof was to nobody and each time the home side, roared on by the crowd in the Dinamo Arena, came right back.
"Maybe it was too good a start and subconsciously we sat back way too much and wanted to hold on to the lead".
Temperatures have been soaring in Georgia this week and heat could be an issue with the game kicking off in the early evening.
That famous win over Germany ultimately secured a play-off berth for Ireland as they mounted an irresistible late surge, and it seems likely that will be the best for which they can hope this time around if they do not beat Serbia.
"We [Bournemouth] probably had a little bit more of the ball than [Ireland did] but against technical, very good players we would want to impose ourselves a lot better than we did last night and it's time for everyone to reflect".
"I don't think there's a quick fix to it".
"The second half was improved and we had three good chances to win the game, but unfortunately one just didn't drop in for us".
Although Ireland had chances to snatch victory, O'Neill told Sky Sports: We didn't play well enough in the first half and Georgia were better than us.
O'Neill made his move with 29 minutes remaining when he replaced the Bournemouth midfielder with winger Aiden McGeady, whose two goals in Tbilisi three years ago clinched a vital Euro 2016 qualifier victory.
The visitors improved after the break and James McClean and substitute Aiden McGeady both had late chances to win it as Vladimir Weiss' men exhausted, but justice would hardly have been served had either of them done so.
"We will try to make the last game hard for Serbia".
After Ireland's goal, they defended as if it was the 90th minute for the remainder of the game.
Duffy, 25, said: "I am delighted but everyone would say they would rather get three points for their country".
You ask that to any manager after a poor enough result and worse performance and you're going to get an inevitably cutting reply but O'Neill has dealt with these questions a lot and he's dealt with them from O'Donoghue specifically a lot.
Jano Ananidze's chip in the tenth minute over pretty much the entire Irish squad but just out of the reach of Otar Kakabadze was the warning shot, as no Irish player felt the need to rush the man with the ball, and Georgia began to get more comfortable and cute. They were by far better side. We've got one or two very, very decent players who probably didn't play well tonight. Martin O'Neill said post match that his side will have to put "their heart and soul" into Tuesday's crunch tie.
