Achrekar, who honoured with the Dronacharya Award in 1990 and the Padma Shri in 2010, was instrumental in coaching Tendulkar, Kambli and over a dozen other top cricketers.
Tendulkar was speaking after inaugurating the pavilion at the MIG Cricket Club in Mumbai, which was named after him.
India have won 3 bilateral away series against South Africa, Australia and New Zealand with only defeat coming against England.
Tendulkar recollected how the revered coach asked him to go back to his original low grip after advising him to hold the bat higher.
Achrekar was cremated in Mumbai on Thursday with his most famous ward Sachin Tendulkar in attendance for a tearful adieu.
Renowned cricket coach Ramakant Achrekar was cremated in Mumbai with his most famous ward Sachin Tendulkar in attendance for a tearful adieu.
Tendulkar, along with Achrekar's other wards like Vinod Kambli, Balwinder Singh Sandhu and Chandrakant Pandit, took part in the procession to the crematorium.
Players of both the teams and the match umpires could be seen sporting black armbands at the Sydney Cricket Ground.
Achrekar was conferred with the Dronacharya award in 1990 for his services to cricket coaching and in 2010 was bestowed with the Padma Shri award.
As a player, Achrekar competed in just one first-class match but was instrumental in moulding Tendulkar as a child, often driving him to stadiums on his scooter.
