After suffering a hand injury last season, 32-year-old Casillas has failed to reassert himself as the club’s first-choice custodian and been forced to play second fiddle to Diego Lopez.
The glovesman has previously spoken of his desire to see out his contract at the capital club, but Cazorla believes joining him in north London would be beneficial - especially now Arsene Wenger is keen.
“I’ve told him [I want him to join Arsenal], but so far he has just been curious about my experience in England,” Cazorla told Sport360.
“His situation is very complicated, but he has to make a decision.
“Lots of clubs want him, including Arsenal, but I think that it would be very difficult to leave Real Madrid because of what the club represents.
“He knows what he has [at Madrid] and what he could find at another club.”
Casillas has a contract with Madrid until July 2017. The club legend has made 18 appearances for the Santiago Bernabeu outfit this term, featuring in all 10 of their Champions League fixtures.
