Nottingham Forest is currently in advanced negotiations to sign Sporting CP defender Ousmane Diomande, according to reports from A BOLA and transfer specialist Fabrizio Romano. The Premier League club has tabled an initial offer of €40 million with add-ons that could push the total valuation to €45 million, though Sporting is holding out for a fee closer to €50 million.
The Financial Mechanics Behind the Diomande Pursuit
Sporting CP’s valuation of the 22-year-old Ivorian international reflects a significant appreciation in value since his arrival in Lisbon. The club initially signed the defender from Danish side Midtjylland in 2023 for a base fee of €7.5 million. Over the following seasons, performance-related bonuses—triggered by reaching 30, 60, and 90 appearances—added €5 million to the total cost. Furthermore, Sporting invested an additional €2 million to buy out a portion of the sell-on clause held by Midtjylland, bringing the total investment in the player to €14.5 million, according to A BOLA.

Strategic Context at Alvalade
The potential sale of Diomande comes during a period of high-value departures for the Portuguese champions. Sporting has already navigated the high-profile exits of Morten Hjulmand to Atletico Madrid for a deal worth up to 45 million and Trincão’s move to Al Ahli, which could reach a total sum in the millions. Managing these departures is a priority for Sporting’s leadership, as the club must now source a replacement to bolster a defensive rotation that includes Gonçalo Inácio, Zeno Debast, and Eduardo Quaresma.
Premier League Interest and Coaching Influence
Nottingham Forest’s pursuit is reportedly driven by manager Oliver Glasner, who tracked the defender during his previous tenure in London. While other Premier League clubs, including Newcastle and Crystal Palace, have been linked to the defender in the past, Nottingham Forest has moved to the front of the queue with concrete negotiations. According to Fabrizio Romano, discussions are currently ongoing between the clubs and the player’s representatives to finalize the terms of the transfer.
