The 27 year-old winger posed in the new Arsenal kit and said "I'm so excited to be joining one of the greatest teams in Europe and also in the Premier League."
"I'm so happy to be joining Arsenal. This is a club with great players, a fantastic stadium and huge support. The club has one of the best managers in football and their style of play is recognised and admired all over the world."
"I will do my best to help Arsenal challenge for trophies and make all the supporters happy."
Arsene Wenger was delighted that he had finally captured Cazorla, whose previous team Malaga had failed to pay his wages due to serious financial problems: "He's a great signing who will add significant quality to us. He is a player with good experience at both club and international level."
The Arsenal manager continued: "He is a versatile, attacking midfield player who can play comfortably on either side of the pitch or centrally. He has good pace, is technically gifted and will be a huge asset to Arsenal Football Club. We are delighted that he is joining us."
