Spain coach Toni Grande has taken aim at Chelsea boss Jose Mourinho.
Mourinho has spoken out over the international pressure on Costa and his fitness issues.
But Toni Grande, Vicente del Bosque's No.2, insists Costa will always travel when healthy.
"How could we go without him, the top scorer in England? We would be crazy," he told Radio Marca.
"It was a relief for everyone he scored. He'll be in the next squad if he's healthy."
