Chelsea striker Diego Costa says he is fit to feature against Arsenal and then for the Spanish national team.
Spain face Slovakia and Luxembourg in four days but the 25-year-old insists he is fit to feature for Vicente del Bosque's side.
"I don't think that [a bust-up between Jose Mourinho and Vicente del Bosque] will happen," Costa told Marca.
"Hopefully I'll be fit to play for Spain.
"I played 90 minutes [against Sporting] so it's clear that I'm fine.
"I am feeling better all the time, and it is Vicente del Bosque's decision.
"I work intensively with the physios during the week because I've been carrying some issues for a while now".
