Arsenal were reportedly monitoring Rúben Dias, 29, as they assessed options to strengthen their defence. Real Madrid, Barcelona, and Chelsea also made enquiries last month about signing the defender. However, Manchester City rejected all approaches, making it clear that Dias is not for sale. The club considers the Portugal international, who signed a new long-term contract in 2025, to be a player they will not sell and a central part of new head coach Enzo Maresca’s plans. According to TEAMtalk, Dias is viewed as a key player for the club's future. The centre-back has 79 caps and 3 goals for Portugal, and his current contract is valid until 2029. Transfermarkt estimates his market value to be €55.00m.
