It’s been a bust transfer window for Xabi Alonso’s side, with ten new additions, including the club record £117 million signing of Morgan Rogers from Aston Villa.
According to The Mirror, Chelsea have no intention of letting up just yet and are eyeing a move for FC Porto ‘keeper Costa.
The 26-year-old has been a stalwart for his boyhood club since breaking into the first team in 2019, making 246 appearances across all competitions.
It’s understood that Costa has a €60 million (£51m) release clause in his contract, a fee that Chelsea would be willing to pay.
Costa and FC Porto were back in action over the weekend, beating Torreense 1-0 in the Super Cup final.
He addressed his future after the game, insisting he is still happy at the club: “I’ve been linked with leaving this club for some time now.
“As I’ve done up to now, what I can say is that I’m very happy here and, while I’m here, I will always be the same player and the same person.”
