Chelsea Enter Advanced Talks for Porto Goalkeeper Diogo Costa
Chelsea have entered advanced negotiations with Porto to sign goalkeeper Diogo Costa. The transfer fee is reportedly around €40m, while Porto are insisting on his full €60m release clause. Xabi Alonso is seeking a reliable long-term number one, and Diogo Costa fits the bill.
Diogo Costa is a 23-year-old goalkeeper who has established himself as one of the best in the Primeira Liga. He kept 21 clean sheets in 33 league games for Porto during the 2025/26 season, compared to Robert Sánchez’s 8 clean sheets in 35 Premier League appearances.

clubBayern Munich and PSG are also monitoring Diogo Costa’s situation, which could strengthen Porto’s negotiating position. Chelsea should increase their offer without automatically paying the full clause, as their busy window has required careful squad management.
Diogo Costa’s Role at Chelsea
Diogo Costa would be expected to become Xabi Alonso’s long-term number one and bring stability to Chelsea’s defense. He is a proven international who is comfortable in possession and would suit Alonso’s build-up approach. Costa’s leadership, sharp reflexes, and ability to begin attacks with accurate passing make him an attractive signing for Chelsea.
Competition for the Starting Spot
Diogo Costa would not simply arrive as competition; he would be expected to become the first-choice goalkeeper. Robert Sánchez has delivered some strong performances but has not always provided consistent security. The future of other goalkeepers at Chelsea remains uncertain, making Diogo Costa’s signing a priority.
Transfer Spending and Wage Bill
The transfer fee for Diogo Costa is reportedly around €40m, while Porto are insisting on his full €60m release clause. If Chelsea were to sign Diogo Costa for €60m, it would be a significant investment in their goalkeeping department. The club’s weekly wage bill would also increase, as Diogo Costa would likely command a higher salary than Robert Sánchez.
