Jose Mourinho Speaks Out on Chelsea-bound Diego Costa

Chelsea manager Jose Mourinho is hopeful the man tipped to be his first summer signing in Diego Costa comes through the World Cup unscathed.

The Atletico Madrid striker has reportedly completed a medical with the Blues who are understood to have activated Costa's £32m release clause after his stunning season at the Vicente Calderon.

Costa, who is expected to lead the line for Spain in their attempts to defend their World Cup crown this summer, meanwhile has done little to quell talk of an imminent move to Stamford Bridge.

Although the end of his domestic campaign was punctured by injury, Mourinho is hoping the Spain international comes through this summer's showpiece injury free to ensure he is fit to start the 2014/15 campaign in style.

"I hope (Costa) has a normal World Cup, no injuries, good holidays and I hope next season he can have a fantastic season," wrote in his Yahoo blog, AS report.

"I don't know where, but I hope he can have a fantastic season next season."

Costa himself has suggested a deal with the Premier League club is in place when recently asked by reporters if he will join Chelsea, telling them: "Well, it looks like it."

Costa's Stamford Bridge-based Spain teammates have also done little to dispel suggestions of the 25-year-old's arrival. When asked whether Costa could instantly adapt to life in the Premier League, full back Cesar Azpilicueta told AS: "Definitely! Physically, Diego is very strong and the Premier League is very demanding in that aspect. I'm sure he'll adapt – he can adapt to any situation."

Costa could also be joined in west London by his Atletico teammate Filipe Luis. The powerful full back is wanted by Chelsea, according to his agent, and his club have already made moves to secure his replacements after signing Guilherme Siqueira from Granada.
