Ireland midfielder Josh Cullen insists there will be no complacency in the approach to tomorrow's Aviva Stadium showdown with Luxembourg.
Stephen Kenny's side will be expected to register their first win under his stewardship when they play host to the fourth seeds.
Cullen says the application levels will be at the same levels as in Wednesday's defeat to Serbia in Belgrade.
The Anderlecht player was entrusted with new responsibility in the game and is hoping to build on that back on home turf.
"There's no international team that you can ever underestimate, the approach and mindset of the team will be no different coming into Saturday as it was from coming into the game on Wednesday night," said Cullen. "Definitely there will be no underestimating them from us."
The 24-year-old says the team will not be lulled into a false sense of security by the positive response to their overall display in Serbia with a much-changed side.
He was paired with Jayson Molumby in a new-look midfield with Alan Browne more advanced in a 3-5-2 but there’s no guarantee Kenny will stick with the same system.
"By no means are we getting carried away with the performance, thinking we're there, but there are things that we can look at and analyse and say, 'Yeah, we did certain things well', and I'm sure there are plenty of things we can look at as well and know that there's a lot to work on,” said Cullen.
"We just need to analyse the game and look at the things we did well, and the things that we didn't do so well.
“I think some of our build-up play from the back was good and I think we were a threat, and when we got into good areas with Browney in the 10 and Robbie (Brady) when he came on, there were chances there for us and at times we were good in possession.
"I think we've shown that we can play different formations and whichever one the manager chooses, we've got players who can play those formations so yeah, whichever the manager decides to choose then we'll be ready to go.”
Kenny praised Cullen and Molumby in the aftermath, in particular their fondness for “taking the ball in very tight areas on the half turn”.
Ex-West Ham player Cullen has been revitalised by a link-up with Vincent Kompany in Belgium and said his selection for this fixture was a proud moment.
"To get my first competitive start for my country was a really proud moment for me and my family and of course from the moment he told me I was excited, and looking forward to the game,” he said.
"Any player needs to be playing games to show what they can do.”
