The Indian skipper said former players were free to express their opinions and it was not necessary for him to react to the observations.
"Well, Mark Waugh is free to express his opinion. On my part, I do not bother with such statements," Ganguly said.
In a scathing attack on the Indian team after the series defeat against Australia, Waugh had said in his column that the home team was pre-occupied with the pitch and needed a change in leadership if they were to improve their game.
Ganguly admitted that the collective failure of the top order batsmen in the recent Test series against Australia was a worrying factor for the team.
"It was unfortunate that our batsmen did not score too many runs. But it was heartening to see a couple of them find form in the last Test in Mumbai.
"But I am confident that others will find their form soon. They are all exceptional players with exceptional records," Ganguly said in an interview published in the latest issue of The Week magazine.
