The India legend revealed his thoughts ahead of next month's Super Series between cricket's top-ranked team Australia and the World XI.
"[Warne] plays his cricket the hard way and has the ability to bounce back from the dead. He's God's gift to cricket," Tendulkar told Inside Cricket.
"How many guys can bowl like him and how many guys can be as exciting as him? I'm least worried about what he does in his private life. It's his life. On the field he has delivered incredibly."
But Tendulkar can imagine Australia firing without Warne despite the world champions' loss in England. "They have a very high standard of domestic cricket in Australia," he said.
"We haven't seen many [new] players because it's tough to break into the Australian side.
"But as and when it does happen, I'm sure they will be equally good."
The six-day match at the SCG, starting on October 14, could be Tendulkar's last Test against Warne, if the master batsman recovers from an elbow injury.
Tendulkar has had an elbow injury for more than a year, forcing him out of India's tour of Zimbabwe.
