Twitter has been abuzz all day on Wednesday as fans, fellow cricketers and Indians in general wished their favourite batsman a happy 40th birthday.
Hashtags like #sachinbirthday, #SachinBabaChaalisMore and Sachin Ramesh Tendulkar were trending throughout the day as fans gushed birthday wishes and lavished praise.
Old friend and teammate Vinod Kambli too wished Sachin, reminiscing about their 664 run stand in the semi-final of the Harris Shield semi-final. It remains the highest partnership in any form of cricket in the world.
"One great thing about Sachin is that he accepts challenges in cricket, like opening the innings in New Zealand and bowling the last over in the Hero Cup semi finals," wrote Kambli.
Perhaps the most tender comment came from young teammate Ajinkya Rahane who said he started playing cricket because of Sachin.
"I started playing cricket because I wanted to be like you. Thanks Sachin Paji for being what you are to me," said Rahane.
Here are some of the tweets:
