The Republic were facing defeat to Group D rivals Austria until Jonathan Walters' 85th-minute strike cancelled out Martin Hinteregger's first-half opener.
In the end it was a fair point but we should have been more clinical.
"When the referee first pointed I thought he'd given the goal".
"I think what he means is that you have to have a real strong mentality, be ready for it, be ready to battle through the game, because qualification matches are exactly that, they are tough games to play in and it's really hard work".
Republic of Ireland vs Austria Lineups: After Serbia in the Group D, the Republic of Ireland takes place in the second position of Standing table.
In Group I Artem Besyedin secured a 2-1 win for Ukraine in Finland.
- Robbie Brady has been directly involved in six goals in his last nine internationals for the Republic of Ireland (three goals, three assists).
An Austria side shorn of many of their big names by injury, illness and suspension took the game by the scruff of the neck, just as O'Neill had urged his own players to do in the run-up. Once or twice, I was close to him as well.
"I've seen the replay and the second goal should count. He is probably maturing and using that experience that he has got now of global football a lot more in the games he is playing, whether it be his movement, he's obviously adding goals to his game, which is hugely important". This was one of those occasions as Ireland dispensed with the aim of playing through Austria -something they had struggled to do for an hour - pushed two target men up front and launched the ball forward like long-range mortar attacks.
Walters said: "We're disappointed with how we started and we went one down, but we should have come out with the win [when you consider] the disallowed goal and the penalty". That's all I'll say on that. Referee David Fernández felt that Duffy had fouled Lainer, however, and the "goal" was controversially ruled out. "We said there would be ups and downs in the qualifiers but we're still in it".
