Manchester City are set to make another major move in the transfer market, as the Premier League champions have reportedly reached a full agreement to sign Portuguese goalkeeper Diogo Costa from FC Porto. The deal is valued at €65 million with an additional €10 million in performance-based add-ons, but the negotiations have taken a surprising turn, as Porto is pushing for a player exchange to be included in the final agreement.

Diogo Costa, widely regarded as one of Europe’s top emerging goalkeepers, has been a key figure for FC Porto over the past few seasons. At just 24 years old, he has already established himself as Portugal’s first-choice goalkeeper and a standout performer in both domestic and European competitions. Manchester City have been monitoring Costa for months, viewing him as a long-term successor to Ederson and a player who can immediately strengthen their goalkeeping department.

However, despite the verbal agreement on the transfer fee, FC Porto has reportedly insisted on including a player from City’s first-team squad in the deal. Sources indicate that Porto is interested in bringing in a midfielder or attacking talent to offset the loss of Costa, with names like Kalvin Phillips and Julián Álvarez being speculated as potential options. Such a request has added complexity to what was initially expected to be a straightforward cash deal.

Manchester City’s management remains confident that the deal will be finalized soon, with personal terms between Costa and the club already agreed upon weeks ago. The Portuguese shot-stopper is said to be excited about the opportunity to work under Pep Guardiola and compete in the Premier League, where his distribution skills and shot-stopping abilities are expected to shine.
Porto, meanwhile, sees this as an opportunity not just to secure a record fee for a goalkeeper, but also to strengthen their squad ahead of the new season by acquiring a proven player from City’s ranks. Negotiations are ongoing, but both clubs are optimistic about reaching a final agreement within the coming days.
Should the transfer be completed, Diogo Costa will become one of the most expensive goalkeepers in history, underlining City’s commitment to reinforcing their squad for another push at both domestic and European glory. Fans of the club are eagerly waiting to see how this blockbuster deal unfolds and whether a surprise player will head to Porto as part of the agreement.
