Andre Agassi is keen to continue playing despite defeat to Roger Federer in the US Open quarter-finals on Thursday.
The 34-year-old American has repeatedly been asked when he will retire but feels he has more to offer.
"I'm going to keep going as long as I feel I have a realistic hope of putting together great matches and finding a way to win," he said.
"My gameplan is to play until I can't do it. I believe with that focus, I can still do that."
He added: "Contrary to what it seems like you're hearing, I never had an intention not to play.
"Before I make any plans, I need to have everything settle down and make sure I'm making good decisions.
"And I feel a sense of responsibility and obligation to give back to a sport that's given me so much in my life."
