Chelsea keep a close eye on €35m-rated Primeira Liga goalkeeper

Chelsea have stepped up their attempts to add a new shot-stopper to replace Edouard Mendy. The London giants are prepared to shell out an irresistible €70m bid for Porto goalkeeper Diogo Costa, who is currently starring for the national team at the World Cup.

Despite having already spent well over €250m in the summer, more arrivals are likely at Chelsea in winter as Potter reshapes the squad to his liking. The Blues have reportedly won the battle to land star attacker Christopher Nkunku and stay interested in his RB Leipzig teammate Josko Gvardiol.

Meanwhile, links with Rafael Leao persist as well. And the London giants on the lookout for a fresh face in between the sticks as well, with the futures of both Mendy and Kepa in question.

Mendy has reportedly refused to sign a new deal extension in Chelsea, despite not performing at his peak level this campaign, struggling with form and fitness, and making some high-profile blunders earlier in the campaign. As a result, the London giants are now ready to listen to offers for the 30-year-old goalkeeper.

Meanwhile, Chelsea have already made “first contacts” with Porto about Costa ahead of a possible transfer next summer. Potter wants a shot-stopper who is more comfortable with the ball at his feet to build up play from the back, as he did with his Brighton side. And the Blues are prepared to offer €70m for the Portuguese goalkeeper.
