Diego Costa, the leading goalscorer in La Liga with 11 goals from 10 matches this season, explained opting to play for Spain was a difficult choice for him to make.
"I hope people understand and respect my decision because it has been very difficult," he said. "It was very difficult to choose between the country where you were born and the country that has given you everything.
"I looked at everything and saw that it was right and best to play for Spain because this is where I have done everything. All that I have in my life was given to me by this country.
"I have a special affection. Here I feel very appreciated for all that I do and I feel the love of the people."
