If Spain decides to tinker with the possession-based system that has given it so much success, striker Diego Costa is ready.
Even if the World Cup champions aren't, that suits the Brazilian-born forward just fine too.
Costa says he has fully recovered from a nagging hamstring injury that dogged him over the close of the club season and is ready to seize his chance for the defending champions in his native Brazil.
He just needs coach Vicente del Bosque to give him the chance, starting with the Group B opener against the Netherlands on Friday.
Costa, who scored 36 goals in all competitions for Spanish champion Atletico Madrid, says: "I'm very motivated, I think I'm 100 percent and ready. I can't wait for the competition to start."
