"We made a mistake in this matter but we need to look ahead now. Indian cricket is moving forward and let us stay focussed in that direction than looking back and creating needless problems," Ganguly said in an interview to The Sportstar.
The Indian captain, who did not play in the Multan Test because of an injury, also made it clear that the declaration issue was a closed chapter and said as far as he was concerned it was a "non-issue".
"Much has been said and written on this subject and not all of it was accurate or in good taste. The media and some people need an issue to talk but as far as I am concerned it was a non-issue.
"In the Sydney Test we declared with Rahul (Dravid) in the 90's. As far as I am concerned this incident of Multan is a chapter closed. We are all mature people and know that sometimes we all make mistakes."
Ganguly also said that Yuvraj Singh is the opener for the future for India and he had spoken to him in this regard.
"Let me make one thing clear: Yuvraj is the opener for the future. I have spoken to him in this regard. He is too good a batsman to sit out and we have backed him ahead of S Ramesh for precisely this reason."
