Spain boss Vicente del Bosque has insisted that "no-one has a guaranteed place" in his squad for the World Cup next summer.

However, the 62-year-old does not expect there to be 'too many changes' from the list of players who won Euro 2012.

"It's a long way off. We have a wide range of players who could come. It's a long journey until May. We could have injuries, setbacks... we'll try to be as fair as possible and bring the best," he told Onda Cero.

"The Euro 2012 squad changed 50% from the Euro 2008 squad, but I don't think there will be that much change this time.

"We tried to bring a guy (Diego Costa) to the national team who is loved and compliments all the players we already have. No-one has a guaranteed place."

Spain will enter next summer's tournament as one of the favourites to retain their crown.
