Even after scoring close to 30,000 international runs ever since he started his career, Sachin Tendulkar feels he has not done enough as a batsman.
"I am not pleased yet with what I have done," said Tendulkar, who has scored a record 12,773 from 159 Tests at an average of 54.58 and 16,684 runs from 425 ODIs.
The 36-year-old Tendulkar, in an interview to Wisden Cricketer magazine, said he is now aiming to touch 15,000-run mark in Tests.
"Sunil Gavaskar has told me that I have to get to 15,000 runs. He said he would be angry with me and would come and catch me if I didn't. I admire him so much and to score that many would be a terrific achievement, but that is not the only aim," he said, adding that "to win the World Cup in 2011" is his another ambition.
Australian captain Ricky Ponting, 34, is close to Tendulkar's Test mark with 11,193 Test runs so far.
Tendulkar, earlier described as second best cricketer after Don Bradman in the history of the game by Wisden, said that if anyone comes close to his style of batting is his teammate Virender Sehwag.
"I would say Virender Sehwag comes closest to my style," he said.
