Senegal and France defender Abdou Diallo is being linked with a move from Qatari side Al-Arabi SC to Greek champions Olympiacos, according to transfer data compiled on 10 December 2025.
The 29-year-old centre-back, currently on the books of Al-Duhail SC and on loan at Al-Arabi, is the subject of speculation over a switch to the Greek Super League 1. The reported probability of the transfer remains unclear, with the database listing only a question mark over the likelihood of the move.
Diallo’s current market value is given as €5.00m, a figure that could make him an attainable option for Olympiacos as they assess experienced defensive reinforcements. With no contract expiry date disclosed for his deal in Qatar, there is also room for conjecture that future negotiations could involve either a transfer fee or, in time, a potential free-agent scenario, depending on how his situation at Al-Duhail and Al-Arabi develops.
Born in Tours on 4 May 1996, the left-footed defender has represented both Senegal and France at different stages of his career and is listed primarily as a centre-back. He has built a substantial CV across Europe’s major leagues, featuring for AS Monaco, Mainz, Borussia Dortmund, Paris Saint-Germain and RB Leipzig before his permanent move to Qatar with Al-Arabi in 2023 and subsequent loan to Al-Duhail in 2025.
Diallo’s market value has declined from a peak of €35m during his spell at Dortmund and PSG to its current €5m level, reflecting both age and his move away from Europe’s top five leagues. However, his experience in Ligue 1, the Bundesliga and European competitions is likely to appeal to Olympiacos, who routinely target players with high-level backgrounds.
Should the rumoured transfer materialise, a switch to Piraeus could offer Diallo a route back into European football and a fresh platform to re-establish his reputation at continental level.
