Tendulkar announced his retirement from international cricket on Thursday (October 10). The Master Blaster will play two more Tests, completing a historic 200 next month against West Indies in Mumbai before he bids adieu to the game. He has played at the highest level for 24 years.
Clarke, who has played against Tendulkar on several occasions since making Test debut against India in Bangalore in 2004, saluted the batsman writing a tribute to him in "Herald Sun" newspaper.
"...the only conclusion to draw is that he (Sachin Tendulkar) is the best batsman the world has seen since The Don (Bradman)," Clarke wrote.
"No one has ever or will ever match Bradman's Test average of 99.96. And I don't think anyone will surpass Tendulkar's record of 200 Test appearances when he retires after next month's series against the West Indies," he added.
The right-hander said Tendulkar's longevity and consistency were astonishing.
"His longevity and consistency over 24 years has been astonishing".
"I'm not a huge believer in statistics, but it was hard not to be impressed when Sachin posted his 100th international century earlier this year.
Many batsmen would be happy to post just one Test or ODI ton in their career, given how difficult they are to compile."
He concluded by saying he will miss watching Tendulkar play. And there will never be a batsman like him.
"We will only see one Sachin Tendulkar in our lifetime. While India go on to produce many great cricketers - including the likes of MS Dhoni, Virat Kohli and Virender Sehwag - no one will rival Tendulkar for longevity or public adoration.
"I'll miss watching him. I won't miss playing against him."
