Nottingham Forest Nears €40 Million Signing of Ivory Coast Defender Ousmane Diomande

Core Event
Nottingham Forest are in advanced negotiations to acquire Sporting CP centre-back Ousmane Diomande for a reported €40 million (£34.3 million; $46.2 million). The agreement includes a five-year contract and a medical scheduled for the upcoming Saturday. If the medical is passed, the transfer will be completed and Diomande will join Forest’s defensive line for the new Premier League season.
Background & Context
Diomande, 22, moved from Danish side FC Midtjylland to Sporting in January 2023 after a trial in which he arrived “without any boots” and impressed in borrowed footwear. He has since made 132 appearances for Sporting, scoring seven goals and providing three assists, and accumulated 149 professional appearances overall. Internationally, he earned 16 senior caps for the Ivory Coast, featuring at the 2026 World Cup and the 2023 Africa Cup of Nations-winning squad.
Forest, under new head coach Oliver Glasner, have already signed midfielder Xaver Schlager on a free transfer and midfielder Gustavo Sá for €20 million. Glasner, who previously employed a back three at Crystal Palace, has identified a three-centre-back system as the defensive foundation for his tenure. Current Forest centre-backs Nikola Milenkovic and Murillo dos Santos form the core of that unit, and Diomande is viewed as the missing piece to complete the trio.
Data & Statistics
- Transfer fee: €40 million (potential bonuses could raise the total to €45 million).
- Release clause in Diomande’s Sporting contract: €80 million.

Official Statements & Responses
He expressed confidence in the board’s ability to secure the right players.
Sporting’s representatives have stipulated an upfront €40 million payment, with performance-related bonuses that could increase the total to €45 million and a sell-on clause. The club’s release clause of €80 million remains in place, but they have agreed to accept half of that amount.
Conflicting Reports & Gaps
Two contrasting accounts emerged this week. One set of reports, citing an Athletic article dated July 22, states that Forest were “in advanced talks” and that the deal was “close to being finalised.” A separate report from Portuguese outlet A Bola, referenced by the Nottingham Post, claims negotiations stalled over “payment terms,” leaving Diomande in limbo and missing Sporting’s season-opening match. Neither source confirmed whether the medical has taken place, leaving the final status of the transfer uncertain.
Verbatim Quotes
- “That was one of the things we have been working on — organising the defence so that we can get pressure on the ball,” — Oliver Glasner, new head coach.
- “I have a picture on my phone; it was snowing, and he was wearing a big leather jacket and some slippers. One year later, we sold him to Sporting. It was like a fairytale,” — Kristian Kjaer, Midtjylland sporting director.
What’s Next
If the Saturday medical proceeds without issue, Diomande will sign the five-year contract and become eligible for selection ahead of Forest’s Premier League campaign. The club still plans to add a further centre-back, a right-back and a striker during the transfer window, as indicated by Glasner’s remarks about “preparing for some new signings.”
