Spain forward David Villa has revealed that the squad are well prepared for the World Cup after playing their friendlies in hot conditions in Washington on Saturday.

Villa came off the bench to score a second-half brace to secure a 2-0 victory for Vicente del Bosque's men against El Salvador at FedEx Field.

Although the World Cup-holders were not at their best, Villa has said that the side are now ready for their World Cup opener against Netherlands on June 13 after a "positive warm-up".

"Today it was difficult because of the weather, it was hot and the condition of the grass," Spain's all-time record goalscorer told reporters.

"I think the team started off well and finished well. I think we're prepared to start the World Cup on the right foot. This was a positive warm-up, these are the same conditions we'll find in Brazil.

"It was difficult to maintain a good rhythm, you take two sprints and then you need to rest. But it was positive."

Villa recently signed a deal with MLS outfit New York City, who are the franchise of Premier League side Manchester City.
