Multiple reliable new sources are reporting that Nottingham Forest have submitted a concrete bid for Gustavo Sa. The midfielder remains under contract at Famalicao, but the opening offer has opened the door for discussions between the two clubs - though it is unclear at this stage whether the current bid will be enough to tempt them to part with a prized asset. Nottingham Forest have laid out their intentions, but valuation and timing remain under debate. West Ham and Al-Ittihad are keeping tabs in case talks collapse or progress slows further. Nottingham Forest have recently been linked with Andrei Ratiu, Ousmane Diomande and Xaver Schlager while Famalicao have had no rumoured targets. Want to see how the story develops?
