I watched the game and you're right, Ireland were very average and didn't really deserve the win. Georgia could have be 2 or 3 nil up at halftime, but the famous Irish jammyness in qualifying (plus a superb goal from a certain A. McGeady) saw them through.
The feeling i get over here is that the media aren't fully behind O'Neill, and are a few of bad results away from turning on him. I spoke to Brian Kerr (the former Ireland manager, now pundit) a couple of months ago about the group and , well, his colourful language made it clear he's no fan of O'Neill's!
Add in the divisive figure of Keane, and IMO Ireland could implode if they don't get things right.
