Villa: I joined Barcelona to play in El Clasico
Barcelona and Real Madrid are set for an intriguing battle this season and will meet at the Nou Camp on November 28, with the return fixture to be played just a month before the end of the season, at the Bernabeu on April 17.
"Playing in such a game is what every player wants to achieve," said former Valencia star Villa.
"I am eager to taste the atmosphere. It's an important game for any player. It's part of the reason players come to Barcelona."
