Abdou Diallo, a 29-year-old centre-back, is planning a return to Europe on a free transfer in the summer. The contract of the former Paris and Dortmund player is scheduled to expire at Umm Salal, where he is currently on loan from Al Arabi. Clubs from France, Germany, and England are observing the situation, and consider him an experienced option. Diallo had previously been linked with Nice, Olympiacos, and Anderlecht in December in relation to the summer transfer window.
