Vicente del Bosque backs Chelsea striker Diego Costa injury case after commitment acussations

Spain manager Vicente del Bosque has claimed Chelsea striker Diego Costa went to Spain by his own initiative to undergo a scan despite already being ruled out as injured just to show his commitment to the national team and play down any speculation.

Furthermore, the boss claims that Costa is eager to prove his worth with Spain after a disappointing World Cup and is so frustrated about having being withdrawn twice that he believes someone has jinxed him.

The Chelsea forward traveled to Madrid on 23 March to undergo a scan with Spanish team doctors even though the Blues medical department had already informed Spain about his injury, after the striker suffered a recurrence of his hamstring problems during the 3-2 victory over Hull City on Sunday 22, March.

But having being questioned by teammate and Spain vice-captain Sergio Ramos about his lack of commitment to the national team when he missed the two previous national team games in November, Costa decided this time to travel to Madrid and undergo a scan with their doctors to prove his commitment and that he definitely suffers an injury.

On 24 March Spain confirmed the striker had been withdrawn from the squad due to "a level 1 hamstring tear on the biceps femoris of the left thigh".

Del Bosque has explained the situation during an interview with Spanish radio station Onda Cero, while assuring he never had any doubts about Costa's commitment to his side.

"He has a muscle tear and he was not going to play but the lad wanted to come and be examined by our doctors, to make himself available and so that nobody was suspicious," Del Bosque told Spanish radio.

"As far as I am concerned he didn't have to come because there is maximum confidence in the player and the logical thing would have been not to come but he wanted to be with us. It would be very Machiavellian to think (he is not committed to Spain)"

Asked about Costa's feelings, he said: "He says he has bad luck and that it seems like someone has jinxed him. That's what people say when they are eager to come to the national team and I hope he is able to join us again soon."
