Nayef Aguerd, a 30-year-old Moroccan center-back, will return to Spain to join Real Sociedad for the 2026/27 season after reaching an agreement with Olympique de Marseille. The Basque club will pay 4 million euros for a one-year loan deal with an 11-million-euro purchase option, which is not mandatory.
The operation is subject to the medical examination and final procedures before becoming official. The agreement between the clubs was confirmed on Friday night by Fabrizio Romano, Santi Aouna, and Matteo Moretto, after Noticias de Gipuzkoa reported that negotiations were close to completion.
Nayef Aguerd returns to Real Sociedad on loan
The chosen formula allows Real Sociedad to bring back Aguerd without committing to a permanent transfer at this moment. An initial proposal of 2.5 million euros for the loan did not convince Marseille, but increasing it to 4 million euros helped unlock the discussions.
The purchase option is set at another 11 million euros. As it is not mandatory, Real will be able to assess Aguerd's performance and physical condition during the season before deciding on an investment that would raise the total cost of the operation to 15 million euros.
The center-back was willing to return to Donostia, and his environment had explored various possibilities in LaLiga in recent days. Al-Sadd had also made progress towards his signing with similar figures, but the player's preference tilted the operation towards Real.
Aguerd left West Ham for Olympique de Marseille in September 2025 in a transfer worth 23 million euros. His contract with the French club runs until 2030, giving them contractual flexibility despite agreeing to the loan deal.

Real Sociedad brings back a center-back familiar with LaLiga
This will be Nayef Aguerd's second spell at the Donostia club. During the 2024/25 season, he played 36 official matches in La Liga, Copa del Rey, and Europa League after arriving on loan from West Ham.
His last season was marked by physical issues. With Marseille, he participated in 22 official games and scored one goal, but a surgical procedure in March limited his activity in the final months of the season and ruled him out of the World Cup.
This medical history makes the medical examination crucial before finalizing the agreement. Aguerd rejoined Marseille's preseason activities, but Real must assess his condition before fully integrating him into Pellegrino Matarazzo's team. It is worth mentioning that Real Sociedad is also attempting to convince Real Madrid to loan Endrick.
Real Sociedad highly satisfied with his work
This signing will cover the departure of Duje Caleta-Car and bolster the defense, addressing one of the remaining positions in this transfer window. Aguerd seems set to become Real Sociedad's first official signing of the summer.
If he passes the scheduled medical tests in the coming days, Nayef Aguerd will travel to San Sebastian to complete his return and begin his second stint in LaLiga. The decision on the 11 million euros purchase option will be made at the end of the 2026/27 season, depending on his performance during the loan.
