Cazorla still playing through pain after Villarreal appearance
The 33-year-old came on as a substitute in a 1-1 draw with Hercules on Tuesday, making his first appearance since October 2016.
Cazorla's six-year spell at Emirates Stadium came to an end at the conclusion of 2017-18, after a series of debilitating injuries kept him on the sidelines.
However, the Spain international admitted after the match that he did not enjoy his appearance, and will not feel like a footballer until his health improves.
"I am only thinking about getting rid of the pain as soon as possible because I am not enjoying what I am doing," Cazorla told Marca.
"I want to train with my colleagues again and to feel like a footballer. It is hard to express what it feels like to be out on the pitch after so much time.
"To feel like a footballer again, to feel the love of the people and the reception they gave me."
