Ousmane Diomandé Joins Nottingham Forest for €40 Million

Ousmane Diomandé is set to become the latest statement signing in Nottingham Forest’s rebuild, with Sporting Portugal agreeing a €40 million deal for the powerful centre-back, according to David Ornstein of The Athletic.

The 22-year-old is expected to fly to England as early as Saturday for his medical. If all goes to plan, he will sign a five-year contract and drop straight into a defensive unit being quietly, and expensively, reshaped.

Forest pay big to beat the market

Sporting only tied Diomandé down to a new contract at the start of this year, running to mid-2030 and protected by an €80 million release clause. On paper, he was one of the least attainable young defenders in Europe.

Yet Sporting have now agreed to let him go for half that figure. For Forest, it is still a major outlay. For Sporting, it is a spectacular piece of business.

They signed the 1.90m defender from FC Midtjylland in January 2023 for a fee between €7.5 million and €12.5 million. The Danish club also negotiated a 20 per cent sell-on clause, ensuring they too will feel the benefit of his rapid rise.

Even with that slice heading to Denmark, Sporting will bank a huge profit. Diomandé becomes the latest high-value departure in a summer that is reshaping their balance sheet as much as their squad.

A new spine at the City Ground

Forest have not been shy in the market. Diomandé is expected to line up on the right side of a back three, alongside Nikola Milenkovic and Murillo dos Santos, giving the club a physically imposing, ball-playing defensive core.

He will also find a familiar face in the dressing room. Compatriot Ibrahim Sangaré, formerly of PSV, is already in place, offering a ready-made link for the young defender as he adjusts to life in England.

The move continues a targeted strategy. Earlier this summer, Forest brought in holding midfielder Xaver Schlager on a free transfer from RB Leipzig, a coup given his pedigree, and paid €20 million to land attacking midfielder Gustavo Sá from FC Famalicão.

Piece by piece, a new spine is being assembled. Diomandé is the most expensive component yet.

Sporting cash in on a golden window

For Sporting, this is turning into a historic transfer window.

Diomandé’s sale is their fourth major windfall of the summer. Geovany Quenda has already gone to Chelsea for €50 million. Morten Hjulmand moved to Atlético Madrid for €40 million. Francisco Trincão headed to Al-Ahli, also for €40 million.

Those headline deals have been supplemented by further exits. Alisson Santos’ permanent move to Napoli brought in another €16.5 million, while Diogo Travassos joined SC Braga for €5.5 million.

The numbers are staggering. The model is clear. Develop, showcase, sell high, reinvest.

Forest, meanwhile, are betting that €40 million on a 22-year-old centre-back is the kind of gamble that keeps them not just in the Premier League, but moving up it.
