Andersen started playing youth football with Aalborg Freja, before moving to Aalborg BK (AaB) at the age of 10. In September 2008, Andersen went on a one week trial at Liverpool at the age of only 14, without getting offered a contract. He penned his first professional contract with AaB in September 2009.
Andersen made his debut for AaB on 5 March 2011 at the age of 16 years and 174 days, making him the youngest player ever to play for AaB in the top-flight Danish Superliga championship and the second youngest player ever to play in the Danish Superliga. One month later, he extended his contract until 2013. He slowly became a regular part of, as he played 22 league matches for AaB in the 2011/12 season. He broke his toe in November 2011 and was out for the rest of the fall. According to a Danish source, Andersen was followed by Liverpool and Ajax in the January 2012 market. This was later confirmed by his agent.
Andersen was usually employed as a right winger, but was capable of playing on the left, as well as an attacking midfielder/playmaker behind the forwards. He was touted as the most promising player to come through the AaB youth ranks since Jesper Grønkjær, by AaB director of football Lynge Jakobsen A number of foreign clubs wanted to sign him by 2012, but Lynge Jakobsen did not want to sell Andersen at too young an age.
On 31 August 2012, Andersen signed with Ajax for an undisclosed fee, with a view to join the squad of Jong Ajax at first. AaB's good relationship with Ajax, having sold Jesper Grønkjær to Ajax as well, was emphasized by Lynge Jakobsen as a reason for the deal materializing. Andersen made his debut 8 December, coming on as a substitute against FC Groningen.
On 8 January 2012, he was called up for the Denmark League XI national football team for their matches in the 2011 King's Cup. With his age of only 17 years and 4 months, he is the youngest player ever to have been a part of the Danish League XI squad.
