Career
He is the twin brother of IFK Göteborg player Jakob Ankersen. Getting his football education in the youth ranks of local team Esbjerg fB, he saw limited first team opportunities, and in the summer of 2010 he decided to join Vejle Boldklub in the Danish 1st Division. After two successful seasons for Vejle, both of them in the Danish 1st division, bigger teams started to pay him attention.
In March 2012 he was sold to Norwegian club Rosenborg BK. He became a regular 1st team starter for the Norwegian side, but after only 18 games he had yet to settle personally.
In the same summer he was sold back to his childhood club Esbjerg fB on a 4-year contract. The goal was shortlisted for the 2013.
On 17 May 2013 he was called up for the Danish National Team for a friendly against Georgia. In the match he remained an unused sub for the entire game.
On August 14, 2013, he made his international debut in a 3-2 loss to Poland, coming on as a substitute for Nicolai Boilesen at half-time.
Ankersen has never represented any of the Danish national youth teams.
