Daniel Agger had a good record in front of goal while he was with the Denmark national team for a period of eleven years. The ex-Liverpool and Brondby central defender scored 11 goals in 75 matches for Denmark before he retired in 2016.

Agger played his first game for the Denmark team in June 2005 during a friendly game with Finland in Tampere. He played the entire duration of the game in a 1-0 win. His first goal for the team arrived some months later against Malta in a World Cup qualifier ahead of the tournament in Germany. He was on target in the 6-1 win over Malta but the result eventually counted for nothing after Denmark failed to qualify for the World Cup tournament on German soil.

The ex-Liverpool defender scored once in eight games for Denmark in the qualifiers ahead of the 2010 FIFA World Cup tournament on South African soil. His goal came in the 3-0 win over Malta at home. At the tournament in South Africa, he scored an own goal in a 2-0 defeat at the hands of the Netherlands in the opening group game for Denmark. Agger and his Danish teammates failed to progress beyond the group stage in South Africa.

He led Denmark out for the first time in a friendly against Germany in August 2010 which ended in a 2-2 draw. Daniel Agger was given the armband permanently one year later. While he was the skipper, Denmark qualified for the 2012 European Championship in Poland and Ukraine.Agger was a regular as Denmark crashed out of the Euro 2012 tournament at the group stage.

Malta were the favourite opponents for Daniel Agger as he scored a brace in a 6-0 victory in what was a 2014 FIFA World Cup qualifier. He retired from international football in 2016.
