According to Voetbal International, FC Köln is the latest club to express interest in Dallinga, who has also attracted attention from Werder Bremen. The 26-year-old has previously played in the Netherlands, France, and Italy, giving him valuable experience in different European leagues. Dallinga's current club, Bologna, is open to working with FC Köln on the transfer, including the possibility of a loan deal with an option to buy.

FC Köln is keen to move quickly on the transfer, in order to prevent other interested clubs from making a move. The German side is looking to sign Dallinga on loan with an option to buy, which would allow them to assess his abilities in the Bundesliga before committing to a permanent deal. With Werder Bremen also in the running, FC Köln will need to act swiftly to secure Dallinga's services.
