The 28-year-old missed out on the 2010 tournament through injury, with his country going on to win the tournament for the first time in their history.
"World Cup 2014 has an extra meaning for me," he told Arsenal Player. "Spain ended up lifting the trophy and not being part of that is still at the back of my mind.
"There's nothing like playing in the World Cup and representing your country. I hope I can experience that and I hope the Spanish national team can bring a bit of happiness to the country."
Spain will visit Equatorial Guinea for a friendly on Saturday, before playing South Africa on November 19.
