Ibrahimovic has agreed to join LA Galaxy in recent days.
The 36-year-old has now revealed that the option to play for Sweden again is there if he wishes to take it.
"If I feel well, capable of giving what I can, the door will always be open. If I want to I'll be there, if not no,' he told the official MLS website.
"I want to play football, we'll see what happens. They call me every day, they ask me how am I doing, but we need to take a step at a time. I repeat if I feel well and if I want to, I'll be there."
