Brazilian-born striker, Diego Costa has turned his back on his country of birth in-order to represent Spain in a controversial move.
The Atletico Madrid forward has rejected an offer to play for Brazil in their upcoming November friendlies and will be available for selection by Spain manager, Vicente del Bosque.
Costa, 25, has represented Brazil before but as they were only in friendlies has been able to change his allegiance.
Costa has been in remarkable form for his club side this season, leading the La Liga goalscoring table with 11 goals, that is four more than Cristiano Ronaldo and Lionel Messi.
At the start of the season, with Atletico's signing of David Villa from Barcelona, it was largely expected that he would be the one to fill the boots of the departed Colombian Radamel Falcao, who contributed 28 league goals last campaign before his extortionate move to free-spending Monaco.
But it is Diego Costa who has taken on the responsibility. He did score ten goals last season and ten in 16 games while on loan at Real Vallecano in the 11/12 season. But he has already eclipsed that total this year as he looks to push Diego Simeone's side on to a title challenge, something Athletico have threatened to do for a while.
Costa bullied the Real Madrid defenders as he scored the goal which won the Madrid derby at the Bernabeu last month. He is a brutish striker, standing at 6ft2' he will always let the defender know he is about and is not afraid to battle. His power, aggression, movement and clinical finishing make him so dangerous to opponents.
He was also a transfer target of Brendan Rodgers in the summer and revealed he was close to joining Liverpool who launched a reported £20m bid.
The Spanish national team are due to play Angola and South Africa in November and Costa will almost certainly be picked in the squad. But the form of the striker could push his way to the being a starter for the team.
Del Bosque has a whole host of the most talented midfielders in the world to pick from but, up-front he is still unsure of his best option. Roberto Soldado was not included in the last squad after his transfer to Tottenham Hotspur, nor was Chelsea's Fernando Torres.
Manchester City's Alvaro Negredo and Swansea's Michu each started through the middle but are quite different players. Del Bosque regularly plays Cesc Fabregas in the 'false nine' role but it is clear that he has not found his favoured approach.
So maybe Diego Costa has an opportunity to be the striker Spain need to spearhead their assent on retaining the World Cup in Brazil. And what an interesting twist it would be if the Brazilian-born man were to lift the trophy on home soil, for the Spaniards.
