FC Koln is actively working to strengthen its left-back position during the current transfer window. As reported by t-online – Köln on Tuesday, September 1, 2026, the Bundesliga club has Croatian Borna Sosa from Crystal Palace and Dutchman Mees de Wit from AZ Alkmaar on its shortlist.
The search for a left-back is important for FC given the current squad situation. The team is currently without three players: Luca Waldschmidt, Sebastian Sebulonsen, and Timo Hübers, as shown on the injuries list. The next fixture is away at VfB Stuttgart on September 4th, a look at the fixtures schedule confirms the short preparation time.
Who are the candidates for the left side?
Borna Sosa would mark a return to the Bundesliga. The experienced full-back knows the league from his time at VfB Stuttgart. Should a move materialize, he could provide competition for Gideon Mensah. Mees de Wit is being considered as an alternative. The 28-year-old was a regular starter for AZ Alkmaar last season and came through the Ajax Amsterdam youth system. He has also played for the Netherlands U17 national team. De Wit is seen as a Plan B option if negotiations for Sosa fall through.
Where is Patrik Kristal going?
While FC Koln seeks reinforcements, one young talent has temporarily left the club. Eighteen-year-old Estonian midfielder Patrik Kristal has been loaned for this season to Swiss champions FC Thun. Technical Director Lukas Berg explained the decision. "Patrik presented himself strongly in training with the professionals during pre-season and thus earned the chance to prove himself this season with the current Swiss champions," said Berg. During the training camp in Austria under coach René Wagner, Kristal was compared to Said El Mala, highlighting his potential.
What did Patrik Kristal say about the move?
The young Estonian himself sees the move as a logical step for his development. "It was very good for me that I was allowed to complete the entire pre-season with the professionals." Kristal stated. The loan is intended to give him precisely this much-needed playing time in a competitive environment.
How does the attack look?
In the attacking department, FC Koln has already increased competition. The signing of Mikey Moore adds pressure on the existing players, which includes Said El Mala. His performances continue to be closely evaluated. The current squad overview shows a team in development, aiming to be equipped for the upcoming league challenges. The away game in Stuttgart on September 4th will be an early test of the season's mood.
