"I only have the power for the Euro at the moment," he replied on Tuesday when asked if he had changed his mind about continuing.
On the preliminary list of footballers he announced on Tuesday he stressed that preparing any list is tough because it involves making decisions about players,reports Efe.
"I have also experienced being left out of a competition and I put myself in the shoes of others," he said.
He expressed pride at the performance of Spanish teams in European competitions, with Sevilla playing in the Europa League final and the Real Madrid-Atletico Madrid final in the Champions League, but regretted that this will force the national team to train without its full squad until six days before the start of the Euro.
The 2010 World Cup-winning coach revealed he did not have telephone conversations with any players except one, Sergio Asenjo, who is not on the preliminary list.
Two-time defending champions Spain are in Group D of Euro 2016 with the Czech Republic, Turkey and Croatia.
