Arsenal midfielder Santi Cazorla's comeback has been delayed because he has had further ankle surgery.

The 32-year-old revealed the news on social media and said he had been having some pain in his tendon.

Doctors told the Spain international that he should be "satisfied" to walk again after contracting gangrene in his right ankle.

Cazorla last played for the Gunners in October 2016, two months before having his initial operation.
