Leading cricketers and other big names have paid their tributes to international cricket's leading run-scorer.
Sunil Gavaskar, legendary former India opener:
"It is hard to imagine any player in the history of the game who combines classical technique with raw aggression like the little champion does. There is not a single shot he cannot play."
Shane Warne, second-highest Test wicket-taker:
"Sachin Tendulkar is, in my time, the best player without a doubt - daylight second, Brian Lara third."
Cricket legends rate Tendulkar
Kapil Dev, former India World Cup-winning captain:
"It's a sad day but everyone has to go one day. He has given happiness to millions and millions of people and has never been controversial."
Graeme Smith, South Africa Test captain:
"It's always difficult to comprehend how someone like Sachin lives his life. He has always managed his career well, managed to perform under extreme amount of pressure and never had any scandals, which is a credit on him and his family."
Sourav Ganguly, former India captain:
"Don't just think about the talent that he had, because he was born with that. It is the effort that he has put in which is for all young cricketers to emulate. He had all the shots in the world."
Muttiah Muralitharan, Test cricket's leading wicket-taker:
"It's the right time for him to retire - after 200 Tests. Pressure for him has always been more than for anyone else because people expected him to score a century every time he went out to bat."
