The midfielder claims he has asked his Spain team-mate to join Arsene Wenger's side but admits his compatriot's situation at the Santiago Bernabeu is "very complicated"
The 32-year-old shot-stopper has featured in all 10 of his club's Champions League fixtures this season but has failed to make an appearance in La Liga, with Carlo Ancelotti preferring Diego Lopez for Primera Division games.
Madrid captain Casillas claimed in March that he is prepared to see out his contract, which ends in 2017, but Cazorla says his fellow Spain international will consider his future at the end of the campaign.
“I’ve told him [I want him to join Arsenal], but so far he has just been curious about my experience in England,” the attacking midfielder 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.”
