Now 35, the former Arsenal star is on a season-long deal with the Yellow Submarine and his form has the veteran a candidate for Spain's Euros squad.
Cazorla told Marca: "I have no long-term plans, let alone being 35 years old. I will end the season and see how the body reacts because every day the sensations are different.
"I always said that I would come back here to play at the best level and when I realise I am not even 80% I will take a step back and leave room for young people. Today I am happy, but the age is known and the injury remains and every time it is felt more and more.
"I will decide in the summer."
