Vincente del Bosque has insisted that his players are fully committed to Spain after Sergio Ramos criticised some of his fellow squad members on Spanish radio.

The Real Madrid defender openly doubted the commitment of players who pull out of international games due to minor injuries, pinpointing Chelsea's Diego Costa in particular.

The holders need as many of their players available for selection as possible after a slow start to qualifying for Euro 2016. However, Del Bosque rubbished the notion that certain players were not fully focused.

"Nobody is pulling the wool over our eyes," the 63-year-old told reporters. "Sergio himself has left the squad before now with an injury and we have taken him off the pitch as he has had a problem.

"I have confidence in the words of the players. We have run the team well for six years and in the right way that you should treat people.

"The case of Diego Costa is special. The groin injury is in some cases something that you can't fight through. He has eased off in training with his club and so we decided not to call him up. If we doubted him then that would be a bad situation."

Spain take on Belarus at the Bernabeu tonight as they hope to reignite their qualifying campaign.
