Chelsea are closely monitoring FC Porto goalkeeper Diogo Costa ahead of a potential summer move to Stamford Bridge, according to the Mirror.
The Blues are looking to revamp several departments this summer, with the goalkeeping position coming under particular scrutiny in recent seasons.
Danish stopper Filip Jørgensen has been linked with a departure, having reportedly considered leaving the club as far back as January.
Former Chicago Fire goalkeeper Gabriel Slonina is also expected to seek a move away in search of regular first-team football, four years after joining with considerable promise.
That would leave Robert Sanchez as Chelsea’s most senior remaining option, though his own future is not entirely guaranteed depending on incoming arrivals.
The Spanish international has been the club’s first choice for three seasons, impressing at times, including in last summer’s FIFA Club World Cup, but his inconsistency has prompted Chelsea to explore stronger alternatives.
Porto have placed a £51m valuation on Costa, who is contracted to the Estádio do Dragão until 2030 and captains the Portuguese club, according to the Mirror citing Record.
Chelsea face significant competition for the 26-year-old’s signature, with European champions Paris Saint-Germain also identifying Costa as their next potential first-choice goalkeeper.
For newly appointed head coach Xabi Alonso, landing Costa would represent a statement signing, as the Portuguese stopper combines elite shot-stopping with composure and excellent distribution.
Costa proved his quality during the recently concluded campaign, playing a central role in Porto clinching their 31st Primeira Liga title while conceding just 13 goals across all competitions.
He recorded 26 clean sheets in all competitions this season, underlining why he is regarded as one of the finest goalkeepers in European football right now.
At £51m, Chelsea would be paying a significant fee, but for a goalkeeper of Costa’s age, profile, and contract length, the investment would represent sound business for Alonso’s rebuilding project.
