Ten caps, one goal and more impact in the headlines than on the field, the Chelsea forward has simply not lived up to his billing for la Roja
There'll be no tournament football for Diego Costa this summer. What a turnaround it's been. Two years ago, in the run-up to the World Cup, he was a coveted prospect and had two of the favourites clamouring for his inclusion in Brazil and Spain. Spain won that battle.
Since then, he has played 10 times for la Roja and the only goal he's scored for his adopted country came in a routine hammering of Luxembourg.
