Match preview
Following a prolonged period of strong performances and impressive results, Denmark entered last year's World Cup as potential dark horses, but the Red and Whites ended up enduring a tournament to forget in Qatar.
After drawing with Tunisia and losing to France, Kasper Hjulmand's men suffered a shock 1-0 defeat against Australia, meaning that Denmark finished rock bottom of Group D with a solitary point to their name.
Four months later, the Danes kicked off their Euro 2024 qualifying campaign with a 3-1 victory over Finland, courtesy of a hat-trick from 20-year-old forward Rasmus Hojlund, who could be set for a big-money move away from Atalanta this summer.
When Hojlund bagged a first-half brace to put his country in command against Kazakhstan in their second qualifier, it looked as though Denmark would secure back-to-back wins without any problems, but Kazakhstan scored three goals in the final 17 minutes to produce a remarkable turnaround in Astana.
Having registered a solitary draw in their previous 20 matches across all competitions - recording 12 wins and seven losses along the way - Hjulmand's men will be eager to discover some consistency during the upcoming international window.
Northern Ireland could not have dreamed of an easier start to their Euro 2024 qualifying journey, as Michael O'Neill's men faced San Marino - who have never won a competitive match - in their opening clash of the campaign.
A brace from Bolton Wanderers forward Dion Charles saw Northern Ireland claim a comfortable 2-0 victory over San Marino, with the hosts managing just one attempt on target while seeing 28% of the ball.
However, the Green and White Army were brought back down to earth three days later, as they suffered a 1-0 home defeat to Finland, despite limiting the visitors to only two shots on target.
After experiencing a disappointing Nations League campaign - winning one of their six games - Northern Ireland have managed to notch just two victories in their last nine encounters across all competitions, recording two draws and five losses in the process.
In terms of the bigger picture, Northern Ireland have won only four of their previous 15 matches, with their last away victory coming in Luxembourg back in March 2022.
