When confronted with the possible departure of Diomande to Nottingham Forest, Rui Borges stated that the defender is still a Sporting player and did not confirm the player's departure.

According to The Athletic, a deal for Nottingham Forest to sign centre-back Ousmane Diomande from Sporting CP is being finalised for €40m. The 22-year-old Ivory Coast international is expected to travel tonight and have a medical before joining Nottingham Forest on a five-year contract.

Ousmane Diomande is expected to sign for Nottingham Forest with his agency ROOF, and The Athletic reports that agreements have been completed.

Fabrizio Romano reports that Ousmane Diomande's move to Nottingham Forest has resumed and is progressing, with an agreement close. Nottingham Forest is moving to the final stages of a €40m deal with Sporting after there were issues in talks over recent weeks. According to the report, all parties are confident, but final steps are still needed.

According to A Bola, an agreement was established between Sporting and Nottingham Forest for the transfer of Ousmane Diomande to the Premier League, but the deal did not proceed due to disagreements regarding payment terms. Subsequently, after being rested in all preparation matches, Ousmane Diomande was called up by Rui Borges for the opening round.

Negotiations between intermediaries of Sporting and Nottingham Forest regarding the transfer of Ousmane Diomande have encountered setbacks. According to A BOLA, the negotiations stalled due to disagreements over the payment terms from the English club to Sporting. The value was reportedly agreed upon, with the payment method being the main point of disagreement. The outcome is currently uncertain, but an agreement remains possible. Sporting wants at least 40 million euros as a fixed amount, with bonuses that could bring the total to 45 million euros and a percentage of future resale profit. It is also noted that an agreement between Sporting and Nottingham Forest was almost reached in the last days of July, with difficulties attributed to Evangelos Marinakis, the owner of Forest. Marinakis is described as eccentric and difficult to negotiate with. Ousmane Diomande has not participated in any pre-season preparation games and will be absent from the opening match of the season.

According to Maisfutebol, Nottingham Forest’s transfer for Ousmane Diomande did not proceed due to a disagreement over the asking price, and the defender is now expected to stay at Sporting.

Ousmane Diomande was at Sporting’s Alcochete training ground on Saturday and is being kept with other players who could leave, as the club does not want to endanger any transfers with a fitness issue. Record reports there is optimism regarding Diomande's move to Nottingham Forest and states that the transfer is nearing completion. Sporting's demands are a guaranteed fixed amount of €40m plus €5m. A bonus based on a certain event, such as a first appearance, is a possibility. There is confidence in Portugal that Oliver Glasner will sign the player, but a final effort from Nottingham Forest is required.

Sporting CP and Nottingham Forest are in ongoing discussions to finalize an agreement for the transfer of Ousmane Diomandé. According to journalist Sebastião Sousa-Pinto, Sporting CP hopes to receive approximately 45 million euros, including bonuses, to transfer the defender. The negotiations are focused on the structure of the offer, with a fixed part and several bonuses linked to individual and collective performances. It is reported that Ousmane Diomandé has given his agreement in principle to join Nottingham Forest, attracted by the sporting project and the prospect of playing in the Premier League. This personal agreement is facilitating the negotiations between the two clubs. Diomandé's annual salary is 3,460,000 euros.

According to A Bola, Ousmane Diomande's transfer to Nottingham Forest is nearing completion, with only the payment methods and bureaucratic details left to be finalized. The report states that Nottingham Forest's interest in Diomande was always intense and was driven by manager Oliver Glasner, who had previously targeted him while at Crystal Palace. Nottingham Forest will pay €40 million to Sporting, which was the minimum amount for the transfer. Bonuses could increase the deal's value to €45 million, and Sporting will retain 10 percent of any future capital gain from a resale. The transfer is expected to be completed within hours, allowing Diomande to join Nottingham Forest, who are currently training in Portugal.

A Bola reports that Ousmane Diomande is transferring to Nottingham Forest for a transfer fee of no less than a fixed €40 million. Sporting is adding bonuses that could increase the deal's value to €45 million, plus 10 percent of the capital gain in a future sale. The English club continues to try to lower the fixed value. Negotiations are ongoing but are progressing slowly, which is partly due to Evangelos Marinakis, the owner of Forest. The talks continue at a slower pace despite the good relationship between Sporting's general director, Bernardo Morais Palmeiro, and Marinakis. It is not certain that the ongoing negotiations will be successful before Friday, when Sporting faces Nottingham Forest in a pre-season friendly. It is also mentioned that there is strong interest from English football.
