The first offer for Lucas Martínez Quarta, a 30-year-old Argentinian international centre-back, was from Al-Sadd of Qatar, which proposed a loan with a purchase option. This offer was rejected as River wants a sale. In August 2026, reports mentioned a loan offer from Al Sadd that included a purchase obligation of $5 million (approximately €4.7 million). Genoa has also been recently linked with the player. Martínez Quarta, who has 16 caps for Argentina, is contracted to River Plate until December 2028 and has a current market value of €4.50m, according to Transfermarkt. He joined River Plate from Fiorentina in January 2025 for a fee of €7 million. He had previously been sold by River to the Italian club for a reported €13 million in 2020.
