Pelle Mattsson

Silkeborg

Mattsson joined Silkeborg IF at the age of 11 from local partner club ØBG Fodbold. On 7 February 2019, 17-year-old Mattson signed a trainee-contract with Silkeborg, after good performances for the first team in training and in friendly games. Mattsson was supposed to continue on the club's U19 team and occasionally train with the first team. However, Mattsson was called up for three first team games, before he got his official debut for the team on 21 April against Hvidovre in the Danish 1st Division. Mattsson started on the bench, before replacing Ronnie Schwartz in the 89th minute. Silkeborg won promotion to the Danish Superliga for the 2019–20 season. Mattsson made his debut in the highest football league in Denmark on 8 July 2020, the same day he signed his first four-and-a-half-year professional contract with Silkeborg.

On 29 August 2025, EFL Championship club Norwich City announced the signing of Mattsson on a contract until 2028. On 20 September, he made his debut for the club in a 3–2 home defeat to Wrexham in the league. On 21 March 2026, Mattsson scored his first goal for the club in a 1‍–‍0 away win against Charlton Athletic at The Valley.
