Arsenal midfielder Santi Cazorla has endorsed Real Madrid's want-away goalkeeper Iker Casillas, saying that he's still one of the best custodians in the world, reports the Daily Express.
The 32-year-old has endured a difficult year at the Santiago Bernabeu, losing his place in the first-team under the former stewardship of Jose Mourinho.
Mourinho's departure and the arrival of Carlo Ancelotti was expected to see Casillas reinstalled as Real Madrid's number one, but that role has been maintained by Diego Lopez, prompting rumours of the Spain international's growing unrest in the capital.
Gunners boss Arsene Wenger has been credited with an interest in bringing Casillas to the Emirates Stadium, and Cazorla's latest comments will only enhance speculation of a possible Premier League transfer in January.
"Iker is one of the best goalkeepers in the world, he has demonstrated it and will continue to do so in the future," the Arsenal star told AS.
"I played with him [Lopez] at Villarreal and saw how good he was then, just like I've seen Casillas with the national team. Diego is an example in many aspects.
"You can only really give your opinion on it if you are inside the dressing room and I'm far away from the Madrid dressing room."
Arsenal's interest in Casillas was briefly halted when Wenger opted to sign Emiliano Viviano from Palermo on a season-long loan deal in the summer, but if the Real Madrid star became available in the New Year, the north London club would be foolish not to move for him.
