Arsenal have completed the signing of Spain international attacking midfielder Santi Cazorla from Malaga.
Cazorla, who was part of Spain's Euro 2012-winning squad earlier this summer, has moved to the Emirates Stadium after signing what Arsenal have called "a long-term contract".
The fee has also not been disclosed, but it is believed to be in the region of 17 million.
Arsenal manager Arsene Wenger told the club's official website: "Santi Cazorla is a great signing for us. He is a player with good experience at both club and international level, who will add significant quality to our squad.
