The midfielder would not discuss whether he will hang up his boots for the national side after the World Cup.
The title holder became the first team to be eliminated in the group stage of this year’s tournament — and only the fifth defending champion to fall at this hurdle — following losses to the Netherlands (5-1) and Chile (2-0).
Alonso was criticized in his homeland after he said his teammates lacked the hunger to want to retain their title in Brazil — a comment that reportedly did not go down well with his compatriots.PHOTOS: Beautiful people in Brazil | Brazil protests | Soccer fanatics | Fan tattoos
The Real Madrid defensive midfielder dismissed the rumors but refused to talk about his future with Spain, after reports suggested that the 32-year-old would retire following the tournament — a decision he supposedly made prior to the competition.
"I'm still not at that stage where I want to decide. What I want is, unfortunately, to finish this World Cup, go on vacation, disconnect a bit and then do one thing at a time," Alonso told Onda Cero. "Right now I will not touch on that subject."
Although Vicente del Bosque’s side is already out of the World Cup, it will play one more game in Brazil when La Roja take on Australia on Monday.
Alonso insists that the chemistry between the players is as good as it was two years ago — when the team won Euro 2012 — but believes that it was simply Spain’s lack of focus that ultimately led to its elimination from the World Cup.
"I will not say the things that happened in the locker room," he said. "Our deficiencies depend on how you want to understand them. I think it is my perception but also that of many of my colleagues. We did not have the required voltage, or the competitive level against Holland and Chile.
"The co-existence between players from different clubs is the same as two years ago. Everything is much more natural, there are no such tensions that you might think. I hate talking about it."
