There were recent reports linking Mariusz Fornalczyk with SC Heerenveen. The player has stated that he is currently a Widzew player and is focused on that.

Maciej Winczewski has stated on platform X that reports about sc Heerenveen's interest in Mariusz Fornalczyk and a rejected €4.5 million offer from Widzew Łódź are not true. He described the news as being concrete and complete nonsense.

SC Heerenveen's interest in 23-year-old Polish winger Mariusz Fornalczyk is not new, as the Dutch club had scouts observe him last year before his transfer from Korona Kielce to Widzew Łódź. It is reported that the interest has re-emerged and that a specific offer of 4.5 million euro has been made for the winger. It is also reported that Widzew has no plans to sell Fornalczyk and that the player is happy in Łódź. Gazetearena.com recently reported on potential interest from Samsunspor. Fornalczyk's contract with his current club is valid until June 30, 2029. He has been capped 17 times for the Poland U21 team, scoring 3 goals. In the 2025/2026 Ekstraklasa season, he made 31 appearances, scoring 1 goal and providing 4 assists. His July 2025 transfer to Widzew Łódź was for a reported €1.5 million. In May 2025, his former club Korona Kielce reportedly rejected an offer of nearly €2 million from an MLS club.
