The man reportedly on the verge of moving to Chelsea has been speaking about his international footballing allegiance.
In an interview with Spanish newspaper AS, Costa claimed Brazil coach and former Chelsea manager Luiz Felipe Scolari had not contacted him and that he felt at home with the Spain squad as the World Cup approaches.
The latest reports suggest Costa could officially be a Chelsea player as early as Tuesday, after the player completed a medical and the Blues offered his reported release-clause.
But for now Costa is focused on being fit and ready for a World Cup campaign that could see him hailed as the new hero of a country he opted to play for ahead of his homeland.
Talking about his choice, Costa is quoted as saying, “Scolari has never called me by phone. The only coach I’ve talked with is (Vicente) Del Bosque. He cared for me, invited me to lunch.”
But he wanted to make it clear he was still very much a Brazilian by heart, and hoped the country of his birth won the World Cup…if Spain fell short!
“I want to win the World Cup with Spain,” Costa said. “But if I cannot, my second wish is that Brazil wins it.”
The 25-year-old scored a remarkable 36 goals for Atletico last season, and he will be hoping to continue that fine form this summer.
And should the deal to Chelsea be finalised as is expected, Jose Mourinho will have a player who could propel them to league and European glory once more, the striker they have long been crying out for.
