After the convincing win, Root said there is a lot of confidence in the dressing room and everyone is backing each other.
Roy has been a mainstay alongside Alex Hales at the top of England's limited-overs batting line-up since the 2015 World Cup but has struggled of late and scored just 33 runs in his last five one-day worldwide knocks.
The first game between England and Bangladesh at the Oval on Thursday (1 June) will get the eighth edition of the tournament under way. "As far pressure is concerned, it is about handling one game at a time, as you build up to every game, you start becoming a favorite".Recalling the 2013 edition, Kohli believes the team has all the right ingredients to succeed in their title defence in a challenging format where they will face Pakistan, Sri Lanka and South Africa in the group stage.
And Jason Roy, a day after Morgan guaranteed his tournament place, fell for just one - his fifth single figure score in his last six ODI innings.
Meanwhile Root suffered a calf injury while batting. The Tigers hit 342 against Pakistan prior to that collapse against India, with Tamim Iqbal hitting 102 runs off 93 deliveries. Playing at home does that, especially with the kind of cricket England have been playing recently.
"The thing is that we all know that on a given day we can beat anybody".
For Bangladesh, Mashrafe Mortaza and Sabbir Rahman took one wicket each.
"We need more variety in our attack".
Bangladesh will look to opener Tamim Iqbal - a player who has made plenty of runs against England in the past - to put on a show at the top of the order.

The bodies of 19 civilians have been recovered and local authorities have reported more civilian deaths still to be tallied. Lorenzana also warned that many militants may have escaped, despite checkpoints throughout the city and surrounding it.
Bangladesh will aim to emulate their 2015 World Cup win over England, when Mahmudullah's hundred paved the way for a memorable victory at the Adelaide Oval.
The Proteas conceded 102 runs in the final 10 overs of the match played against England in Leeds.
Samuels has a history of on-field spats whether it is Australia's legendary spinner Shane Warner or the English all-rounder Ben Stokes who got punished by Carlos Brathwaite in T20 World Cup 2016 final.
Ben Stokes and Tamim were involved in a verbal altercation as tempers frayed but the left-hander reached his century off 124 balls, including two sixes and 11 fours.
The 28-year-old then went down the pitch to drive Ali for a soaring straight six.
The batsmen had crossed and next ball Mushfiqur carelessly holed out to long-off, with Bangladesh only managing a relatively modest 43 off the last five overs.
Lower down the batting line up, S Rahman's 24 (15) pushed Bangladesh to cross 300 mark.
"(But) Against Bangladesh, I calmed myself down and I thought: "it's an important opportunity for me to go out there and play a few shots".
