[5] Dahl joined Djurgårdens IF on 24 July 2023 on a reported 3 million kronor transfer from Örebro SK, and signing a 4.5-year contract that stretched through the 2027 season.
[6][7] Dahl was initially not considered a clear starter, but rather a backup at the left back position for the more experienced Rami Kaib who had also joined from SC Heerenveen in the summer window.
His play in 2024, blending excellent defensive work with great offensive vision and forming a dangerous partnership with Tobias Gulliksen on Djurgårdens IF's left flank, earned him high praise from the Djurgårdens IF fan base and he was frequently considered the best player on the pitch.
After much speculation during the 2024 summer transfer window, it was announced that Dahl had signed for Serie A club Roma on 28 July 2024, almost exactly one year after joining Djurgården, for a reported €4.3 million fee.
[9] On 3 February 2025, Dahl joined Primeira Liga club Benfica on loan until the end of the 2024–25 season.
