A Sweden international left-back, he joined SL Benfica in the winter 2025 transfer window from AS Roma.

Samuel Dahl began his football journey at Vasteras SK, his hometown club, and in 2020—while playing for the Under-17s—he moved to AIK.

After two seasons in Solna’s youth setup, between the Under-17s and Under-19s, Dahl transferred to Orebro SK in 2022. It was with Orebro that he made his professional debut on March 7, 2022, aged 19, in a Swedish Cup match against AIK. Dahl established himself at Orebro SK and moved to Djurgårdens in 2023, making his first appearance for them on July 27 that year.

The left-back’s upward trajectory went hand in hand with steady progress through Sweden’s youth national teams, culminating in his senior debut on January 12, 2024, in a friendly against Estonia. Dahl’s consolidation as a player reached a new phase in July 2024 when he was signed by AS Roma. At the Italian capital club, he made three appearances up to early February 2025, when he moved to Benfica on loan. At the end of the 2025/26 season, the Eagles exercised the purchase option and Dahl signed a contract valid until 2029.
