Claes Kronberg

Kronberg was born in Nykøbing Falster where he also played for Lolland Falster Alliancen. Kronberg joined Sarpsborg 08 in 2011. He made his debut for Sarpsborg 08 in a 3–1 loss against Lillestrøm. In July 2013 he changed his surname to Kronberg after he married his girlfriend. Kronberg joined Viking ahead of the 2016 season. After the 2018 season, Viking did not renew Kronberg's contract and thus he left the club. On 19 June 2019, Kronberg signed for Sandnes Ulf after training with them for several months. He made his debut for the club the same day when Sandnes Ulf lost 2–1 against his former club Viking in the third round of the 2019 Norwegian Cup. Kronberg moved to Faroe Islands Premier League club KÍ Klaksvík in February 2021, after ten years in Norway. His tenure with the club witnessed remarkable achievements, playing a pivotal role in their domestic triumphs and historic European feats. Notably, he was part of KÍ becoming first Faroese club to advance to the group stage of a major UEFA-organised European tournament, qualifying for the 2023–24 edition of the UEFA Europa Conference League. Additionally, they secured three consecutive league titles in the 2021, 2022, and 2023 seasons.
