RB Leipzig are monitoring Al-Ittihad's Moussa Diaby, a winger who is reportedly preparing to return to European football this summer. The 26-year-old French international is also being monitored by Borussia Dortmund and Atletico Madrid. According to sources, intermediaries have informed Chelsea, Liverpool, Tottenham Hotspur, and Newcastle United of his potential availability, while his former club Aston Villa is also being informed about the situation. TEAMtalk previously revealed that Inter Milan had attempted to sign him in January, and the club reportedly remains interested. Diaby joined the Saudi club in July 2024, has a contract until June 2029, and has provided 2 goals and 6 assists in 22 league appearances this season. Transfermarkt estimates his current market value to be €28.00m. Diaby's move to Al-Ittihad from Aston Villa occurred in July 2024 for a reported €60 million. In January 2026, Al-Ittihad reportedly rejected offers from Inter Milan valued up to €35 million, with their asking price said to be €40 million at the time.
