Alonso has been given a three-week break following Spain's successful Euro 2008 campaign, with his proposed £16million move to Juventus seemingly on hold.
But Alonso admits to having "no idea" where he will be playing next season.
Liverpool boss Rafael Benitez needs funds from player sales to maintain his interest in Aston Villa's Gareth Barry and what is believed to be a player-plus cash offer for Tottenham's Irish forward Robbie Keane.
Alonso told Spanish football expert Guillem Balague's website, >: "I have no idea (what the future holds). Right now I am just thinking about going on holiday, sitting back and relaxing.
"We all need time to sit back and think about what we (Spain) achieved and to take it all in.
"I will be able to think about all that has gone on and what is going to happen regarding my future later on. We will see what happens when I get back."
