England's stand-in captain Jos Buttler praised the solidity and adventure of two more understudies - the untried opening pair of James Vince and Sam Billings - for preparing the ground for a series victory against Bangladesh.
England's successful chase is the highest ever achieved at the Zahur Ahmed Chowdhury Stadium in Chittagong, bettering Bangladesh's 227 for 8 against England in the 2011 World Cup.
Buttler said that the lesson from their poor chase when they were defeated in the second ODI was that they needed to be less tentative, something they achieved in style as they extended a run that now stands at only one defeat in the last 12 ODIs where they have had to chase a target.
Vince and Billings, a new opening pair that had to be cobbled together because Jason Roy couldn't shake off his injury, added 63 in 11.4 overs and, while it may not have shaken Bangladesh too much, it gave the batsmen in the dressing room a lot of confidence.
Vince has not had a great series but had his moments in making 32 he made with five boundaries, even if he could not push on. Billings latched on to anything that gave him room to free his arms as he made 62 off 69 balls, laced with four boundaries and a six.
"I think we probably learnt form the other day when we were tentative," Buttler said. "Guys were made aware of that. We had a good chat before we went out to bat. We wanted to be aggressive. I thought the two guys did that fantastically well.
"You need to get off to a good start. There were partnerships that built and in the end we ran with their momentum. We lost a few wickets that kept Bangladesh interested. We did enough. Chases haven't been high here so to go and do that with a young and inexperienced side is a testament for us."
Buttler said that going into the halfway mark, he knew that they could chase down 278 runs and told his teammates that they should just go for it, regardless of the outcome.
"I didn't it was going to be easy but I was confident. The start was going to be crucial. Even if we did lose, I wanted us to lose in the fashion the way we want to play: be aggressive, take the game to the opposition. The openers set the tone brilliantly," he said.
Buttler said that their Chittagong experience from the 2014 World T20 where the dew was a huge factor in night games, was a piece of knowledge that they used to their advantage.
"Looking back to the 2014 T20 World Cup when we played here, there was a lot of dew. We knew the ball would skid a lot. We knew it would be easier to bat second. It was quite tacky at the start which suited our spinners, who bowled really well," he said.
