"Huge congratulations to Sachin Tendulkar on your 100th international 100. Very well deserved mate. One of the greatest batsmen of all time," McGrath, who has had several on-field duels with Tendulkar, tweeted.
The Australian legend also paid tribute to another Indian veteran Rahul Dravid, who recently retired from cricket. "Congratulations to 2 Indian Cricket Legends, Sachin Tendulkar & Rahul Dravid. I have so much respect for you both," he said.
Tendulkar completed a century of hundreds - 49 ODI and 51 Test - during an Asia Cup match against Bangladesh in Mirpur.
McGrath`s former teammate Lee also joined cricketers world over in lauding the 38-year-old right-hander, whose careers spans over two decades. "Congratulations to Sachin on achieving his 100th hundred," tweeted the bowler, who is currently in the West Indies with the team.
