Guardiola has won applause since his appointment as Barcelona's head coach, having led the team to a multitude of titles.

Under his guidance, Barca won the Primera Liga, Spanish Cup, Spanish Super Cup, UEFA Champions League, UEFA Super Cup and Club World Cup.

The Catalans lost their first competition under the 39-year-old when they were knocked out of the Copa del Rey by Sevilla in January.

Barcelona's form, as such, was negatively affected but Del Bosque believes the Premira Liga titans won't take much time to regain peak form.

"Barcelona have the power of recovery, as they have good habits that can take them where they want to go," he said.

"As for Guardiola as Spain coach? There have been other ex-Barcelona bosses who have took charge of the seleccion before. He would do well, yes."
