Santi Cazorla ruled out for rest of season - reports

The Spaniard has been suffering from an ankle problem and hasn't played since October.

He had surgery last month and was due back in March but suffered a setback which means he will need a further operation.

Gunners boss Arsene Wenger had spoken of the importance of Cazorla to the squad following the news of his injury.

"The dressing room needs a balance between experience and youth-team players and you need to be guided as well by some experienced players as well when you go through difficult times," Wenger said.

"They help you always to keep your feet on the ground and keep focused."
