#1. Diego Costa
Diego Costa’s decision to play for Spain instead of Brazil is one of the most famous instances of a player changing nationality to play international football.
Costa played for Brazil in two friendlies in 2013 but because he played most of his career in Spain, he held a Spanish passport and opted to play for them. One cannot blame him because players like Fred and Jo were ahead of Costa in the pecking order for Brazil under Scolari.
His decision to play for Spain was not received well by Scolari who lashed out at the player. The player made the following statement about his decision to represent Spain.
"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."
He has now scored 7 goals in 19 games for La Furia Roja.
