Maria Sharapova has accepted a wildcard to join the Brisbane International in January.
Despite dropping to No 133 in the world ranking due to a nagging shoulder injury, the 32-year-old is convinced of making a comeback in 2020.
The five-time grand slam champion said retirement was never on her radar.
"To be fair when I was younger I never saw myself playing past 30," Sharapova said.
"(And) I don't think my surgically repaired shoulder will ever be perfect.
"But I still feel there is a lot in me to give. I still have a lot of fire in me.
"As long as the shoulder stays healthy and my body allows me to I hope there is a lot of time left for me."
