His progress in the academy ranks was interrupted by injuries during the following two seasons, but he impressed enough for his scholarship deal to be extended for a third year in 2020.
As a result of Wigan being put into administration in the 2019âÂÂ20 season, and the team's subsequent relegation from the Championship, Aasgaard was promoted to the club's first-team squad along with several other academy players for their 2020âÂÂ21 League One campaign.

In January 2021, Aasgaard signed his first professional contract with Wigan, signing until the summer of 2023. He ended his first season having played 35 times in all competitions, including 13 league starts, scoring three goals.
After the start of the 2021âÂÂ22 season, Aasgaard signed an improved four-and-a-half-year contract, running until June 2026. In July 2023, he signed a further contract extension until 2028.
On 28 January 2025, Aasgaard signed for Championship side Luton Town for an undisclosed fee. On 1 February 2025, Aasgaard made his debut for Luton in a 1âÂÂ1 draw against Sheffield Wednesday.
After LutonâÂÂs relegation from the Championship, Aasgaard joined Scottish Premiership club Rangers on 5 July 2025 for an undisclosed fee which was reported to be ã3.5 million. He signed a contract running until 2029. After an early injury ruled him out of the opening league and European fixtures, Thelo finally made his debut coming on as a second half substitute in a 4âÂÂ2 victory over Alloa Athletic in the Premier Sports League Cup.
Aasgaard was born in Liverpool, England, and is of Norwegian descent through his father, and of French descent through his mother.
He represented the Norway under-16 team three times in 2018.
