Galatasaray keep playing the transfer game, make €20m bid for Diogo Costa | OneFootball

Galatasaray is looking to strengthen their goalkeeping position and Diogo Costa from FC Porto has emerged as the latest target for the Turkish champions.

According to journalist Florian Plettenberg, the Istanbul club has made an official offer of 20 million euros, plus bonuses, for the goalkeeper.

Diogo Costa is seen as an alternative to Ederson, who remains Galatasaray's priority, but an agreement with Manchester City is not yet in sight.

The 20 million offered represents half the market value of the national team's starting goalkeeper, according to Transfermarkt, a portal specialized in player evaluations.

In the 2025/26 season, Galatasaray lost the historic Muslera, who went to Argentina to play for Estudiantes. In his absence, 34-year-old Guvenec has been taking the position in the Istanbul club's goal, but the management is seeking a definitive solution.
