Sheffield United boss Chris Wilder has confirmed a formal offer has landed for midfielder Gustavo Hamer, with the bid coming from one of the 29-year-old's former clubs.

Hamer has been strongly linked with a return to Coventry City, the side he made 132 appearances for before departing for the Championship rivals. According to BBC News, Wilder acknowledged the interest is genuine, verifying that a proposal has been tabled, though he stopped short of revealing further specifics on the fee or Sheffield United's stance.

The report does not confirm whether the Blades are willing to sanction a sale, leaving Hamer's future at Bramall Lane uncertain for now. Given his history with Coventry and the fact a bid is now on the table, speculation over a potential switch back to the Sky Blues is likely to intensify in the coming days.
