Sorry. Spin bowling is as old as cricket. There were other great offspinners before Prasanna. One example is Laker. I cant think of others offhand. England don't play spin well. They are getting away with their improved bats. As regards Australia, they were always weak against good offspin. I don't know what you know of the history of cricket. Prasanna played in the 1960s and 70s. Test cricket is being played since 1877. The googly was invented in 1895. If spin was in its infancy in the 1960s and 70s, it took a long time growing up.
