Chelsea striker Diego Costa feels he a owes Spain goals after his national team recall.

Costa is desperate to prove himself to coach Vicente del Bosque.

"I think what's missing is that I need to score goals. Every time I'm getting better physically, I know I can give a lot more to the team and hopefully that will start right now.

"Strikers need to score goals, that's what I've been lacking here. When I score, my confidence will be higher and everything will come together. We have very skilful players and I don't have any excuses, I have to do things better. I'm getting to know my teammates better and although the style is different for me there are great players here. I need confidence, adapting to this style is easy."
