Villarreal midfielder Santi Cazorla admits he is still hurt by his Arsenal departure.
Indeed, the 34 year-old says he regrets never getting to say a "proper goodbye" to the club he misses so much.
"When you are at a big club like Arsenal, sometimes you don't realise what it means to be there until you are gone," he told the Independent.
"I never got to say a proper goodbye. It was the biggest team I played for in my career and I miss everything about Arsenal."
But he hasn't given up of playing there one last time, after a six-year career at the Emirates which came to an end last year.
"I don't know what my legacy is there, you would have to ask the fans, but I want to say thank you to them all. I would like to play at the Emirates one last time before I retire.
"I don't know what I will do afterwards - maybe a coach, maybe a sporting director - but I would love to go back to Arsenal. I lived in London for six years. My son loved it there. In the future, we will see if I have the possibility."
