Vicente del Bosque insists Spain do not need to make drastic changes going forward as they look to recover from a disappointing World Cup campaign.

The reigning world champions brought their time in Brazil to an end with a 3-0 victory over Australia to finish third in Group B.
Defeats to Netherlands and Chile saw La Furia Roja crash out of the competition after just two games, and there have been calls from many for a major revamp of the squad as attentions turn to qualifying for Euro 2016.
Del Bosque, however, is adamant that Spain already have a platform to build on going forward, while he has backed his set of players to return stronger.
"There are still people here who can help the team a lot and we will have to be watchful. I wouldn't eliminate anyone due to age," he told a news conference.
"In six years with Spain, we have always been first in the rankings. I think it is a generation of kids who have been great. Now it has been our turn to lose and we must lose with our heads held high.
"For the future of Spain, we'll have to do something. We have a good base, our players are not veterans yet , good young players, so we have to be calm in the face of the future."
Goals from David Villa, Fernando Torres and Juan Mata gave Spain victory on Monday, but Del Bosque was left to rue his side's previous two performances.
"We closed out our World Cup participation in a dignified fashion. The players played at the highest level, then we took control of the match," he said.
"We have to think that we were a little bit below our level and that Netherlands and Chile played really well, they were tough rivals."
There has also been speculation over Del Bosque's future after the World Cup, but he remained coy when asked of his plans.
He said: "No, I have no time frame . Nor does the [Royal Spanish Football Federation] president. We will talk with no drama, with stability, without sensation and we will do what is necessary."
Meanwhile, Villa, who said earlier this month that he is to retire from international football after the World Cup, has revealed that he would love to play on for Spain if asked.
"I have always said I would like to play for Spain since I was a little kid but I am aware that it is not possible to play forever," Villa, who has signed for New York City FC, said. "Now after the World Cup I will take some months off, and it's complicated for me, I would play forever but we shall see.
"I would play with the national team until I was 55 if I could, but it is impossible and we have to be realists. If the coach wants to call on me, I would love it, but it is difficult and we have to be realists."
Villa added on the defeat of Australia: "For me playing for Spain always gave me great happiness. We knew we had to put our game face on to go out with a win against Australia. Of course I am happy to have participated in the first goal but we are also sad because we didn't get to spend much time here."
