Andre Onana's successor decided! Porto prepare for bidding war as Man Utd join Man City in bid for €75m goalkeeper Diogo Costa

According to Correio da Manhã, United have identified Portuguese goalkeeper Diogo Costa as a potential replacement for Onana. United’s scouting network has already been deployed to monitor Costa’s performances. Representatives from the club were recently present at Estádio do Dragão to observe the 24-year-old in action during Porto’s match against Famalicão.

The chase for Costa's signature is not limited to the red half of Manchester, though, as City are also reportedly preparing a move for the Portuguese shot-stopper as they consider reinforcements to cover for Ederson, who has struggled with recurring injuries this season. Pep Guardiola’s side are expected to initiate formal talks soon, with a €58 million (£50m/$67m) offer reportedly in the works.

Porto president André Villas-Boas is well aware of the growing demand for Costa and is reportedly prepared to sanction a move - but only on his own terms. Sources suggest that he would consider a transfer, provided that the fee offered comes close to the goalkeeper’s full release clause €75m (£58m/$86m).

Any departure would only occur after the Club World Cup this summer. This strategy is seen as a way for Porto to fully capitalise on Costa’s market value, with the tournament set to provide a global stage for the goalkeeper. Villas-Boas hopes that standout performances in the USA could further drive up interest and potentially increase the financial reward from any sale. The Dragons are set to face Palmeiras on June 15, followed by matches against Inter Miami on June 19 and Al-Ahly on June 24.
