Cricket legend Sunil Gavaskar expressed hope that Sachin Tendulkar would one day come out with his autobiography detailing little known matters about his life and career.

"One day, hopefully, Sachin Tendulkar would himself sit down and write his story so that we will know exactly what made him tick," Gavaskar said after releasing a book titled "Sachin Tendulkar: A Definitive Biography", written by 'Mid-Day' assistant editor Vaibhav Purandare.

Gavaskar said a lot of biographies on Tendulkar have been written in various languages apart from English, but he wanted to know some little known facts about the master batsman which no book so far had revealed.

"Like, for example, we would all like to know in which language does he converse with his wife Anjali, who is part Gujarati and part English, or with his children.

"Is it Marathi, Gujarati, English or some other language," the former India captain remarked.

"We all know that Tendulkar uses a heavy bat, but would like to be informed about the number of grains his bat has or the number of handle grips he prefers to bat with," he said.

Gavaskar sounded very emotional after having attended the funeral of former Mumbai all-rounder Sharad Diwadkar, who passed away in Mumbai on Tuesday, and said the large turn-out for the last rites of Diwadkar showed he was a well-loved man despite not having been a great player.
