Nottingham Forest are on the verge of completing one of the most significant deals of the summer transfer window after reaching an agreement for Sporting CP defender Ousmane Diomande. The Ivory Coast international has been a target for several elite clubs across Europe, but the Reds have moved decisively to secure his signature.

Nottingham Forest are making a monumental statement of intent, shattering their transfer record to secure Ousmane Diomande, a defender with the pedigree to transform their backline. This €40 million move signals a clear ambition from the club and manager Oliver Glasner.

Key Points:

  • Nottingham Forest are finalizing a €40m deal for Sporting CP's highly-rated center-back, Ousmane Diomande.
  • The 22-year-old Ivorian international is expected to sign a five-year contract after his medical.
  • Diomande brings a winning mentality, having secured back-to-back Primeira Liga titles and the Africa Cup of Nations with Ivory Coast.
  • This marquee signing is a cornerstone of Oliver Glasner's strategic squad rebuild at the City Ground.

Forest's Ambitious Defensive Coup Takes Shape

The City Ground is buzzing with the news that Nottingham Forest is on the verge of landing Ousmane Diomande from Sporting CP in a staggering €40 million transfer. This substantial investment, equivalent to approximately £34.3 million, underscores Forest's determination to reinforce their defense under new head coach Oliver Glasner. The deal is reportedly in its final stages, with Diomande scheduled for a medical this Saturday before committing to a long-term five-year contract.

The arrival of a talent like Diomande is precisely the statement of intent Forest needed after a challenging previous season. His impending signing will inject quality and much-needed steel into the heart of their defense, a crucial step as Glasner molds his squad.

From Lisbon to the Premier League: Diomande's Meteoric Rise

At just 22 years old, Ousmane Diomande boasts an impressive resume that belies his age. He joined Sporting CP in January 2023 for an initial €7.5 million and swiftly became an indispensable part of their success. During his tenure, he played a pivotal role in Sporting securing back-to-back Primeira Liga titles in the 2023-24 and 2024-25 seasons, alongside lifting the Taca de Portugal in 2024-25.

His impact extends to the international stage, where Diomande has earned 16 caps for Ivory Coast. He was a key member of the squad that famously lifted the Africa Cup of Nations trophy in 2023, featuring alongside current Forest midfielder Ibrahim Sangare. Known for his impressive physicality and composed ball-playing ability, Diomande is perfectly equipped for the rigors of the Premier League.

Glasner's Vision Takes Shape at the City Ground

This high-profile Nottingham Forest transfer news signifies the club's robust backing of Oliver Glasner's strategic vision. Following a disappointing 16th-place finish last season, Forest are eager to empower their manager to implement his high-pressing, dynamic style of play. Diomande's blend of potential, European experience, and immediate quality makes him an ideal fit.

The Ivorian defender is not the only new face at the City Ground this summer. Forest have already secured the services of midfielder Xaver Schlager on a free transfer from RB Leipzig, adding tactical discipline and energy to the midfield. These shrewd acquisitions reflect a clear commitment to build a competitive squad capable of climbing the Premier League table. Glasner's track record, including his proven success at Crystal Palace where he showcased his cup-winning prowess and ability to elevate a team's performance, has clearly inspired confidence.

Building for Longevity: Beyond New Signings

Beyond incoming talent, Nottingham Forest has been proactive in securing its existing key assets. Midfield lynchpin Ibrahim Sangare recently penned a new deal until 2029, while promising defender Murillo extended his contract until 2030. This dual approach of attracting top-tier talent like Diomande and retaining crucial figures demonstrates a comprehensive strategy for sustained success. The revitalized squad will aim to make an immediate impact when they kick off their Premier League campaign at home against Leeds United on August 22.
