According to Voetbalprimeur.nl, there is transfer interest in Gustavo Hamer as he enters the final year of his contract at Sheffield United. He has previously been linked with PSV and is also the subject of interest from Premier League clubs. A price of about eight million was rumored earlier, partly because of his contract situation.

PSV is considering whether to make a concrete move for Gustavo Hamer, who is open to returning to the Eredivisie to prove himself at the top level. Sheffield United's manager, Ruben Selles, expressed his desire to keep Hamer, stating he wants him to remain a key player at the club. However, he acknowledged the uncertainty of the transfer market. Hamer is valued at eight to twelve million euros. Transfermarkt currently estimates his market worth at 16.00 million euros.
