Diego Costa has reportedly suffered a setback in his bid to make the Spain squad for Euro 2016.
The Chelsea striker recently picked up a hamstring injury - something that has plagued him for the last two seasons.
According to AS, the complaint means that the 27-year-old is now a doubt to be fit in time for the start of the tournament.
The report adds that if Costa misses out, head coach Vicente del Bosque is likely to turn to Atletico Madrid centre-forward Fernando Torres to fill the void.
Costa has scored one goal from his 10 appearances at senior international level.
