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

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

According to journalist Florian Plettenberg, the Istanbul club has submitted 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 top 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 website specializing in player valuations.

In the 2025/26 season, Galatasaray lost their legendary Muslera, who moved to Argentina to play for Estudiantes. In his absence, Guvenec, 34, has taken over as the club’s goalkeeper, but the management is looking for a definitive solution.
