An advantage for FC Köln over Boro could be the club's position in the Bundesliga, as 23-year-old Otto Rosengren dreams of playing in Germany's top flight. According to Rosengren, he will consider a move if something concrete is in place. He also said he thinks the German league would have been a good fit for him and that moving abroad is a step most players dream of.

1. FC Köln want to sign Otto Rosengren, and the club's officials made a trip to Sweden to watch him play live. According to Expressen, Boro and 1. FC Köln are the current favourites to sign Rosengren, and the outlet makes no mention of any other teams. Expressen is not certain how this situation will develop. It is not clear whether the German club will make a formal bid. Otto Rosengren has a contract until December 2027. FC Köln’s interest, along with his contract situation, allows Malmö FF to secure a large transfer price.

Alongside RB Leipzig, FC Schalke, and TSG Hoffenheim, 1. FC Köln has also shown interest in 23-year-old Malmö FF player Otto Rosengren. The Rhineland club has entered the competition for the player and has made contact with his representatives. Middlesbrough FC is also particularly interested in signing the Swedish central midfielder, who has one cap for his country. With one and a half years left on his contract, Rosengren is expected to be sold this summer. Köln's interest is driven by the need to find a replacement after losing two players in central midfield. The player joined Malmö in July 2023 and has a market value of €3.00m, according to Transfermarkt. In the 2025/2026 Allsvenskan season, he has made 11 appearances, scoring one goal and providing three assists.
