FC Köln has signed Jakub Kaminski for 5.5 million Euro. The 23-year-old Polish player was a key player for the promoted team during his loan spell. "Kuba has impressed us with his personality from the first conversations. He is down-to-earth, ambitious and an absolute team player. In the past season, he has demonstrated these qualities every day on and off the pitch. Therefore, it was quickly clear to us that we would exercise the purchase option", said FC sports director Thomas Kessler. "His development and performances are at the same time a very good example of how FC Köln is an excellent address for ambitious players to develop on a high level and take the next step in their career", Kessler added further. After seven goals and five assists in the just-ended Bundesliga season, the market value of the all-rounder has risen to 17 million euros. In the contract with Köln, a release clause of 20 million euros is to be anchored after his fixed engagement. Given Kaminski's recent development, it is no longer ruled out that another club will meet this. In recent days, rumors have been circulating about a possible Premier League transfer. Media in his Polish homeland reported on a concrete offer from the island. However, the exact club remained unclear. According to reports, Kaminski has already internally lodged his change of heart in Köln. Already last year, he explained to the Premier League: "It's just the best league in the world - with high tempo and high intensity. The fans live football in England. That would already be a dream." A possible Kaminski departure would certainly keep the Effzeh busy over the summer. After all, they would then bring in a lucrative transfer bonus.
