Youngest Test debutant from first 8 Test playing nations

#3 India- Sachin Tendulkar, 16 years 205 days

Sachin Tendulkar in Pakistan, 1989

Now, this one is regarded as the most inspired selection brought about by India's team of selectors in the history of the sport and despite misgivings about selecting a 16-year-old for a tour to Pakistan, they stuck to their guns. The rest, as the cliché goes, is history, as the 16-year-old Sachin Tendulkar went on to become the greatest batsman in the world since Sir Donald Bradman and certainly, the greatest in India's history.

He struggled on his Test debut and found it tough to adjust to the pace of the Pakistani bowlers, but eventually, he found his feet in international cricket. Tendulkar made 15 on his debut innings, however, over the next 24 years he became the highest run scorer in Test history and also holds the record for the highest number of Test centuries.
