Following his departure from Arsenal, he has made 35 appearances across all competitions this season, scoring six goals.
Cazorla has described his return to first-team action as a "difficult journey" but now feels like he has been able to put his injury nightmare firmly behind him.
"I worked really hard to recover my best form," he told Omnisport. "Recovering my best form has always been my only target, otherwise I would have retired.
"You never know how you feel until you're back in really competitive games, and game by game I've been gaining my best form. I've been playing more and more minutes until I forgot about my injury and my performances on the pitch improved.
"Nowadays I'm really close to my very best. I still have margin for improvement, but I never thought I would have got back to this level one year ago.
"Now I value everything much more. I enjoy each training session and every time I board the coach to reach the stadium, I remember the bad moments I lived through and what a difficult journey it was to go back to playing football."
