Shane Warne truly believed that even though Joe Root is a great player, he is not the best captain. Warne, who ruled the leg spin department back in the days felt that it's Jos Butler who could be a better captain than Joe Root and he would be happy of Jos is the captain of the Test Team.
He also mentioned that he has spent some time with Butler this year and truly believes that he is a very mature player and if he comes the captain of England, it would only add more value to the entire team. As far as Root, the batsman was concerned, he had no problems with him other than his conversion rate.
When asked who he thinks will win the ICC World Cup 2019, Warne took no time to answer that one. He felt that it would be India or England who would be the eventual champions.
