"I probably first heard Sachin's name in the early '90s. The one thing that always stuck in my mind about Sachin was that his size never ever matched his status," Hayden wrote in a book 'Sachin -- Cricketer of the Century' by Vimal Kumar, which will hit the stands in the first week of March.
"He was an incredibly slight man for someone who was such a huge brand within the game. It wasn't until I really played against him that I understood that there was a tiger that lay within him: he was a very competitive little man," he said.
"My favourite Sachin moment was at the Mohali Test where he broke the world record for the most number of Test runs. There was so much excitement around the ground that the fireworks actually stopped play for the better part of 20 minutes, whilst the smoke cleared away," he recalled.
Writing in the same book, former Australian coach John Buchanan compared Tendulkar with Australian great Ricky Pontinh, who happened to be a contemporary of the Indian.
"Statistically, Tendulkar has a better record than Ricky Ponting. If Tendulkar is far more orthodox, far more classical and technical, Ricky is a little more unorthodox," he explained.
