Porto goalkeeper Diogo Costa, 25, has agreed to join Manchester City ahead of the 2025-26 season, according to multiple reports including Foot Mercato and confirmed by sources close to the negotiations. The move is expected to take place once the summer transfer window opens.
Costa’s agent, Jorge Mendes, is playing a key role in ongoing talks with Manchester City.
The Portuguese keeper has a €75 million release clause in his Porto contract, valid until 2027.
While the clause stands at €75 million, City believe they can negotiate a fee closer to €50 million to secure the transfer.
Manchester United had also shown interest but are reportedly unable to match the financial terms or compete with City’s offer.
Manchester City’s current number one, Ederson, has faced a challenging season marked by injury setbacks and inconsistent shot-stopping performances.
Ederson’s future at the club is uncertain, with links to a potential summer move to the Saudi Pro League.
Costa is viewed as the ideal replacement, combining excellent shot-stopping ability with strong distribution skills that suit Pep Guardiola’s style.
His clean sheet record and error-free performances this season have impressed City’s sporting directors.
If the transfer goes through, Diogo Costa will likely become Manchester City’s new first-choice goalkeeper, with Ederson possibly departing during the summer window. This signing aligns with City’s strategy to refresh key positions following a difficult 2024-25 campaign and to maintain their competitiveness at the highest level.
The deal is expected to be finalized soon, with City eager to avoid last summer’s recruitment missteps and strengthen their squad early ahead of the new season.
