'I've worked with Jos a bit this year, and I think he's someone who would make an excellent captain, ' said Warne, of Buttler.
Shane Warne's mesmerising bowling prowess coupled with his personal life (which has always been fodder for the tabloid press) has made him one of the world's most illustrious sportsmen. Root doesn't have the best conversion rate whereas Jos Buttler has recently made a fine comeback to the Test cricket.
"He'd love to have more hundreds to be able to be spoken about in the same sentences as Virat Kohli and Steve Smith", he said. "We're sponsored by a beer company and England aren't very good".
"Maybe England could think about their best player having the shackles off, not having the responsibility of captaincy, and give it to someone like Jos Buttler", he added. Jos could play with his freedom and captain the side, and Joe could just concentrate on his cricket. If he totally 100 per cent concentrates on his cricket, his batting and nothing else, then maybe we might see Joe Root become the best batsman in the world.
It is therefore, hard to sum up the Warne's journey in a few words which is why he has launched his new autobiography titled, "No Spin", which contains the true stories behind the headlines and challenges some of the enduring myths and untruths that surround the legendary cricketer.
But while the 49-year-old Australian reinvented the art of leg-spin bowling, his life has also been laden with "guilt" and "regret" over the pain his colourful personal life caused his family.
Moreover, Shane Warne also thinks that Joe Root is the best England's player.
Disgraced pair Steve Smith and David Warner will be back from their ball-tampering suspensions in time for that series and Warne expects both men to regain pivotal roles in Australia's set-up.
"To do it first ball in an Ashes series, I look back and say, "yes" it was a fluke but I think it was meant to be".
'It's going to be tough for them at first.
'Forgiveness takes time, but there's nothing like making a couple of hundreds in a row and people thinking, "Oh, we've missed this guy". "The Australian batting revolves around them".
"Two of our top five batsmen in the world, Warner and Smith have been banned for 12 months".
'They have to be aware that they're in for a bit of a hostile time around the world until they've earned the respect back.
"I'm embarrassed and hurt that I let them down as their father and as a husband to Simone [Callahan] I wasn't very good".
