The Danes were on course to have other engagements for this international window having been 3-2 up on aggregate with four minutes to go against Portugal in an Nations League quarter-final showdown back in March.
However, Brian Riemer’s side couldn’t withstand the Portuguese onslaught and lost 5-3 on aggregate, thus missing out on a place in the Nations League finals.
Northern Ireland enjoyed a successful Nations League campaign themselves. Topping a group that also included Bulgaria and Belarus to earn promotion to League B, losing just once along the way.
That said, the visitors may fancy their chances of recording a first-ever win on Danish soil given the hosts have only won once in their last five outings.
