Karachi (Munirul Haq)Pakistan squash legend Jahangir Khan who is famous for winning 555 matches in a row, a record in any sports, but a new book (Jahangir Khan 555) has cast doubt on the figure and says it might be much lower and could be less than 500.In Jahangir Khan 555, authors Rod Gilmour and Alan Thatcher say nobody was keeping proper records during Khan’s 51/2-year unbeaten run from 1981 to 1986.But Jahangir Khan said that his tally could be more ( 600-700) if you add invitational, exhibition and challenge matches because 555 is only tournament matches.
