Once the initial euphoria of the win in Wales began to die down, Ireland fans started looking to see who we might face in the playoffs.
After results around Europe over the weekend, and taking into account how we are going to be placed in the soon-to-be-update FIFA World Rankings, it became apparent that Croatia, Italy, one of Portugal or Switzerland, and potentially Sweden were our possible opponents.
What immediately followed that was inevitably a discussion on who we do and don't fancy, and even the RTÉ panel got in on the act with Eamon Dunphy stating that he doesn't want to see us draw Portgual, while Liam Brady said he'd love to see James McClean put it up to Cristiano Ronaldo.
For the players, this discussion also took place in the dressing room in Cardiff, but as Cyrus Christie has revealed to Mark Pougatch on BBC Radio 5 Live, the attitude was a bit different.
While Irish fans may have been worried about the dangers a Cristiano Ronaldo or a Luka Modric could cause us along with their talented teammates, the Irish players were - or at least one of them was - confident of beating anyone.
Listen, we'll take whoever we come up against. We'll go into the game positive and confident.
There was a message after, the gaffer said who we could end up against, and one of the lads shouted out 'We'll beat them as well.'
There's a lot of confidence in this squad. We are a tough team to play against, we don't give any teams many chances, we keep clean sheets, I think it was 6 or 7 clean sheets in this qualifying campaign which is remarkable really, and we know we can win games as well.
We know our strengths, we know our weaknesses, and we stick to our gameplan, and it seems to work for us.
Yeah, we're going to need to find out who shouted that. Brilliant stuff.
It's exactly what we want to hear from the players. Leaving the worrying about other teams to the media and fans, they know they are capable of showing up when it matters most.
Gab Marcotti echoed the sentiments of Christie after pointing out that Italy had already qualified by the time Ireland faced them at Euro 2016:
I think maybe a better example is what happened in the next game against France. Obviously they lost, but it looked to me at least watching the game 'My goodness, Martin O'Neill is about to knock out the hosts' because is certainly the way the game was going for long stretches.
I think that the fact that they don't really seem phazed whoever they play - often players said what Christie just said, we don't mind, you figure it's just player talk - but no, with them it's really real. They really don't give the impression that they care who they are facing.
Fear nobody.
There will be no easy games in the playoffs, and we will find out whoever we must face on Tuesday, October 17th.
And we'll beat them as well.
