Nottingham Forest have made an enquiry to Sporting for centre-back Ousmane Diomande, according to reports. Sporting are said to have received the request from the English club as Forest explore possible defensive reinforcements. The reports do not specify whether a formal bid has been submitted or what fee or contract terms, if any, are being discussed. No details are provided about Diomande’s availability or whether Sporting are willing to negotiate at this stage. With only an enquiry reported, the next step would typically involve clarification of interest, potential valuations, and the player’s position in Sporting’s plans for the coming season. The story is currently limited to the fact that Forest have reached out for Diomande; further updates would be expected if negotiations progress beyond the initial enquiry.
