Chris Wilder stated that a discussion has taken place between Sheffield United’s head of football administration, Carl Shieber, and Gustavo Hamer's agent, adding that he has not been significantly involved. Wilder also said that he thinks they have initiated the process, and it is for them to determine what the approach or enthusiasm from Hamer is, what his ambitions are and where he sees his future. According to a report from Ben Jacobs on January 13, Hamer could leave Sheffield United before the end of the transfer window, with the club willing to accept a fee of as little as £6 million. Cremonese have been linked with the 28-year-old.

Ben Jacobs via X reported that Gustavo Hamer, a 28-year-old Dutch-Brazilian central midfielder for Sheffield United, has interest from clubs abroad. The report also stated that Cremonese, Trabzonspor, and Sevilla are reportedly interested in a potential £6m deal this January. Hamer has 18 months remaining on his contract, and Sheffield United could potentially decide to sell him during the current transfer window. In the 2025/2026 Championship season, Hamer has made 18 appearances, contributing 2 goals and 3 assists. Transfermarkt estimates his current market value at €16.00m. Reports from mid-2025 cited an asking price from Sheffield United in the range of €21 million to €24 million.
