The two former captains, who were in Canada to raise fund for an NGO, also dispelled the notion that the Indian master blaster was a spent force.
"Sachin is still the legend of the game. He has served his country for nearly 15 years with tremendous success. He played more than 100 Test matches," Waqar said.
"He is a dedicated cricketer and I think he will stay in the game for many more years," the former fast bowler added.
Waqar also sprang to the defence of a beleaguered Shoaib Akhtar saying the speedster had a great future ahead.
"Shoaib will be playing for Worcestershire this season and I hope he will prove his worth as a genuine and effective pace bowler," he was quoted as saying by The Dawn.
Akram also told the same newspaper that "they (Tendulkar and Shoaib) are young. And they both have great desire to perform even better in days to come".
The two fearsome former bowlers auctioned a cricket bat and a ball in their fund raising drive.
