The Spain international has been a target for the north London club for the last couple of weeks, with the Emirates Stadium side making the most of Malaga’s financial difficulties.
Despite a delay completing the deal, Arsene Wenger has expressed his delight that Cazorla has joined his squad.
“Santi Cazorla is a great signing for us,” the French coach told the Gunners’ official website.
“He is a player with good experience at both club and international level, who will add significant quality to our squad.
“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,” Wenger concluded.
Cazorla meanwhile has also admitted his delight at the deal being completed and is looking forward to getting started with his new club.
“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’m so excited to be joining one of the greatest teams in Europe and also in the Premier League. I will do my best to help Arsenal challenge for trophies and make all the supporters happy,” he stated.
