&nbsp; A video of television interview of late Indian captain Mansur Ali Khan Pataudi's wife Sharmila Tagore explaining the reason why she asked former Australia captain Ian Chappell to give a speech at the Raj Singh Dungarpur World Cricket Summit in place of what would have been Tiger Pataudi's welcome address. &nbsp; Chappell paid glorious tributes to legendary cricketer Mansur Ali Khan Pataudi, who passed away on September 22 this year. &nbsp; "His (Pataudi's) abilities could have been used to the full extent. He had a wonderful knowledge of the game and had the ability to give more to cricket. I know he had some role to play in the IPL and was a match referee but he could have been used more wisely given his vast experience as a player," Chappell said during the Raj Singh Dungarpur World Cricket Summit. &nbsp; The 70-year-old cricketer, who scored 2793 runs in 46 Tests, led the team to victory in nine matches, including India's first overseas win against New Zealand.
