The legendary Indian cricketer in a tweet expressed his gratitude to Achrekar, saying, "Guru is the one who removes the darkness of ignorance in the student. Thank you Achrekar Sir for being that Guru & guide to me and making me what I am today."
The Dronacharya awardee has trained Tendulkar and Vinod Kambli among others at Shivaji Park in Dadar.
The stalwart mentor passed away at 87 years old in January this year.
Upon Achrekar's passing, Tendulkar said that his childhood coach had built the foundation of the master blaster's cricketing career.
"Cricket in heaven will be enriched with the presence of Achrekar Sir. Like many of his students, I learned my ABCD of cricket under Sir's guidance. His contribution to my life cannot be captured in words. He built the foundation that I stand on," Tendulkar said.
"Last month, I met Sir along with some of his students and spent some time together. We shared a laugh as we remembered the old times. Achrekar Sir taught us the virtues of playing straight and living straight. Thank you for making us a part of your life and enriching us with your coaching manual. Well played Sir and May you coach more wherever you are," he included.
Viewed as one of the best batsmen ever, Tendulkar holds the record of being the most astounding run-scorer ever in the international cricket, having indented up 18,426 runs in ODI and 15,921 keeps running in Test matches.
Meanwhile, former India batsman Virender Sehwag conveyed his wishes on Guru Purnima through Twitter.
"May the Darkness be dispelled. Happy #GuruPurnima!" Sehwag said.
