Bologna have officially sent Thijs Dallinga to FC Koln on loan with an option to buy at the end of the season for what should be a total deal worth €14m.

The striker completed the transfer today with a statement from the Rossoblu confirming that there is an option to make it permanent in June 2027.

Dallinga struggled at Bologna

According to various sources including the Corriere di Bologna and Sky Sport Italia, the loan will be at a cost of €1m, with the option to buy for a further €13m at the end of this season.

The Dutch centre-forward just turned 26 earlier this month and had made the move to Bologna from FC Toulouse in 2024 for €16.2m, but he never really found his feet in Serie A.

There were 12 goals and eight assists in 80 competitive games for the club, last season just five goals in 37 appearances.

Dallinga represents the last piece of the domino effect in Serie A, which started with Mateo Pellegrino going from Parma to Fiorentina, then Roberto Piccoli from the Viola to Bologna.
