William Elgaard Kaastrup (born 21 March 2004) is a Danish footballer who plays as a left-back for Danish Superliga club Randers FC.
Club career
On 21 January 2023, Randers FC confirmed that the club had signed 18-year old Kaastrup from F.C. Copenhagen, effective from the summer of 2023. Five days later, however, Randers confirmed that the clubs had agreed on a deal that sent Kaastrup to Randers with immediate effect instead. Kaastrup signed a deal until June 2026.
After a few appearances for Randers' U19 team, Kaastrup made his official debut for his new club on 23 April 2023 against Brøndby IF, replacing Adam Andersson for the last few minutes.
