Republic of Ireland v Denmark past meetings
The Republic of Ireland and Denmark go head to head in Dublin on Tuesday evening with a trip to the 2018 World Cup finals in Russia awaiting the victors.
Here, Press Association Sport takes a look at some of their previous encounters.
Republic of Ireland 2 Denmark 1, World Cup qualifier, October 1956
Having been drawn in a group along with the Danes and England, Ireland got their campaign off to the perfect start when Dermot Curtis and George Gavin fired them into a 2-0 half-time lead over Denmark in their opening tie at Dalymount Park with Aage Rou Jensen's late strike too little to deny them victory. Ireland would win the return leg 2-0, but having lost 5-1 in England and then drawn 1-1 in the reverse fixture, their qualification hopes had already been dashed.
Republic of Ireland 1 Denmark 1, World Cup qualifier, October 1969
After the initial clash had been abandoned because of fog with the score at 1-1 a year earlier, when Johnny Giles' penalty had dragged Ireland back into it, the teams reconvened in Dublin in October 1969. Don Givens scored in a 1-1 draw when they game was replayed and his strike secured the only point Ireland won in the entire campaign.
Denmark 3 Republic of Ireland 3, European Championship qualifier, May 1978
Goals from Frank Stapleton and Tony Grealish handed the Republic a 2-0 lead inside the opening 25 minutes in Copenhagen before Henning Jensen pulled one back. Gerry Daly's 65th-minute strike restored the visitors' advantage, but Benny Nielsen's penalty and Soren Lerby's piledriver ensured the spoils were shared.
Republic of Ireland 1 Denmark 4, World Cup qualifier, November 1985
It all started so well for Ireland when Stapleton handed them a sixth minute lead at Lansdowne Road, but Preben Elkjaer's double and goals from Michael Laudrup and John Sivebaek eased the hugely talented Danes to victory. The campaign proved to be something of a watershed for Irish football with manager Eoin Hand's departure paving the way for Jack Charlton's arrival.
Denmark 0 Republic of Ireland 0, World Cup qualifier, November 2017
Irish pragmatism proved a match for Danish flair as the Republic returned from the Parken Stadium with a first leg 0-0 draw in their play-off showdown. They did so thanks in large part to a string of fine saves by keeper Darren Randolph, who denied Jens Stryger Larsen, Andreas Cornelius, Christian Eriksen and Yussuf Poulsen to preserve his clean sheet.
