England's captain Eoin Morgan believes cricket's three formats are diverging at a rate that will soon make it impossible to have a single national coach across Tests, ODIs and Twenty20 matches.
BBC Sport looks at why England can be considered favourites to win the series less than two years on from their miserable World Cup showing.
Morgan said Root is an important player for the squad. "They're good one-day bowlers and a good one-day outfit so it's a good challenge".
Sam Billings, Jason Roy, David Willey and Buttler have been playing in Australia's Big Bash T20 competition, while Morgan, Alex Hales, Liam Plunkett and Adil Rashid took part in the inaugural T10 League in the United Arab Emirates last month.
WHEN England appointed Trevor Bayliss it was to achieve success in white-ball cricket as much as anything else.
Asked if they might enjoy better results than their Test colleagues, he said: "I hope not".
England's attack isn't as formidable but contains considerably more variety than their popgun Test arsenal led by quicks Mark Wood, Liam Plunkett and brilliant spinner Adil Rashid - the leading ODI wicket-taker of the past three years.More news: After a warm Saturday, temperatures to drop again

Joe Root is set to be fit to play in the opening game of England's ODI series against Australia on Sunday, captain Eoin Morgan has confirmed.
Their only options, if they were to sack him, would be to do so at the end of this winter (to do so next summer would surely be a risk too far in respect of those World Cup aspirations) or else go down the split coaching route and have a separate head of the Test team, a path that the governing body are understood to be reluctant to take. During the same period, Australia reached 300 12 times in 50 matches, including 10 out of 23 matches batting first.
Since the Champions Trophy, Australia has won only five out of the 15 matches they have played.
Warner was absent from the Australian training on Friday as well. On the composition of the team, Smith said, "The middle order has probably been where we have had a bit of an issue".
Hales could be involved for the first time since being suspended for his involvement in an incident in Bristol in September, which saw team-mate Ben Stokes arrested on suspicion of causing actual bodily harm. "It's not often you get free rein and ambition to be adventurous as you like".
Taylor expects Moeen Ali to have "more of an impact" in the one-day series, following a torrid Ashes with bat and ball. More importantly, the wickets that we've played on, we've adapted to them. "As does Paul Farbrace - he's very positive and they are a good combination".
