FC Köln faces a busy transfer summer as numerous squad issues need to be addressed. So far, there have been no new signings, with only three previously loaned players being permanently acquired. The club has already spent around 14 million euros, limiting financial options. No lucrative sales have been realized yet, complicating the situation further. Overall, at least six players could leave the club. Squad planning is therefore a challenge that needs to be tackled. In goal, Marvin Schwäbe is the undisputed number one, while Ron-Robert Zieler serves as the backup. In defense, there are several question marks, especially in central defense, where new players like Jahmai Simpson-Pusey and Rav van den Berg are under contract. The coming weeks will be crucial in solidifying the squad structure for the next season.
