Shane Duffy, Chiedozie Ogbene and Callum Robinson got on the scoresheet as the Republic of Ireland breezed past Luxembourg to secure third spot in Group A.
This was only Ireland’s second competitive victory from their previous 15 games. They finish third in their group behind Serbia and Portugal.
Stephen Kenny’s future is set to be discussed and Ireland’s positive end to the campaign boosted his hopes of keeping his job.
Luxembourg played a significant part in that dreadful start when they won 1-0 at the Aviva Stadium in March, but although they had a goal correctly chalked off with the score at 0-0, they rarely threatened a repeat in front of a capacity crowd of 9,268 at their new stadium.
In front of FIFA president Gianni Infantino – who was booed loudly by the crowd – and Luxembourg’s Grand Duke Henri, it was Luxembourg goalkeeper Ralph Schon who was first into the action, diving to his left to palm away Robinson’s dipping ninth-minute strike after the excellent Ogbene had been played into space down the right and delivered an inviting cross.
Adam Idah appealed unsuccessfully for a 14th-minute penalty after going down under defender Vahid Selimovic’s challenge, and Ogbene went similarly unrewarded three minutes later after Maxime Chanot appeared to tug at his shirt after he had burst past him.
The pace of Ogbene and Robinson and the width provided by James McClean were causing Luxembourg real problems, although the wrong-footed Gavin Bazunu had to react smartly to acrobatically turn away Olivier Thill’s attempt from distance after it had clipped Josh Cullen on its way to goal.
Gerson Rodrigues, who had scored five of his side’s eight goals for the campaign before kick-off, was keeping the Republic of Ireland rearguard engaged with his clever movement and trickery while Thill was busy in midfield, but with little or no end product.
But Schon needed strong hands to divert Ogbene’s rising drive over five minutes before the break and then claw away John Egan’s header with Ireland looking the more likely to force their way in front.
Idah flicked a Jeff Hendrick cross wide with Robinson perhaps better placed behind him and the Newcastle midfielder screwed a shot wide from Matt Doherty’s through-ball as Ireland resumed with real purpose.
Doherty blasted high and wide from long range with the momentum increasing, although it might have died with 54 minutes when the home side thought they had taken the lead.
Danel Sinani was well into his celebration after thumping Laurent Jans’ cross past Bazunu, but Hungarian referee Tamas Bognar ruined his evening by blowing for a foul on Duffy by substitute Maurice Deville during the build-up.
Luxembourg’s misery increased 22 minutes from time when, after Selimovic had been penalised for a foul on substitute Jason Knight, he then got his head to Josh Cullen’s free-kick, but could only help it on to Duffy at the far post and he powered it into the net from point-blank range.
It deepened seven minutes later when Hendrick picked out Knight’s run into the box and he audaciously back-heeled it square for Ogbene to lift the ball over the advancing Schon, and was complete with two minutes remaining when Knight turned McClean’s cross back across goal for Robinson to tap into an empty net.
