See ya!
England captain Jos Buttler: "That was a fantastic series win. Bangladesh are a formidable team at home, we are delighted to get a series win.
"We spoke about ways we could improve from the last match and I thought we did that really well today. Jason Roy led with the batting and guys chipped in around him and then a fantastic start with the ball.
"As spoken about, these are probably the conditions we would find the hardest as a team and to play like we did today is a fantastic achievement. From one to 11 the guys stood up and I thought the standard and intensity we played at was much higher than the first game, and that's what we strive to get to.
"We've talked a lot in the dressing room about adapting to conditions and being a team that can play in a variety of ways. When we turn up in Chittagong we are going to have to assess the conditions and play accordingly. But there are lots of guys putting their hands up."
Player of the match, England opener Jason Roy: "I've spent a lot of time playing a lot of cricket in the subcontintent, when I was younger doing training camps, and today I had to dig deep with those skills and put it on the field.
"I needed to give myself an opportunity today. In the first game I had a rush of blood and played a pretty poor shot against the spin. Today I made sure I batted time and made sure I gave myself the best opportunity to score runs.
"It was an unbelievable effort to put on over 300. Jos [Buttler] and I rotated the strike really well. All three of Jos, Moeen Ali and Sam Curran scoring as freely as they did was an incredible effort. They showed a lot of skill."
Bangladesh captain Tamim Iqbal: "I think I was a bit disappointed with the way we started with the ball and the first four or five overs.
"And then we had an opportunity to bring them down, we missed a run out. But they batted well, Roy batted exceptionally well. Buttler batted as well.
"So yes I am disappointed to lose the series.
"When you lose a game like this you can point a lot of fingers at a lot of people. But I'm not the kind of person to do this. We just didn't click as a team today. It was not the fault of any individual.
"When you lose three wickets in the first two or three overs it becomes very difficult. When you're chasing 326 at some time you have to go. I thought my shot didn't quite come off, but when you're chasing 326 someone has to take a risk.
"We would like to finish the series on a high, it is very disappointing we lost the series, but credit must go to England."
Bangladesh captain Tamim Iqbal has just been speaking at the post-match press conference.
He's called Jason Roy's performance "expectational".
Full quotes to come.

Taskin run out (Moeen) 21 (Ban 194-9)
And he's gone! Taskin Ahmed doesn't ground his bat sprinting a quick single so has to walk when Moeen takes out his stumps with a rocket from mid-off.
Chance of a run-out after a Moeen Ali direct hit. It's all go in this over.
Ban 194-8
Off the elbow. That doesn't count as being part of the bat and so Taskin survives.
Ban 194-8
Taskin goes for a pull shot, doesn't quite connect but the ball pops up into the air and Jos Buttler dives to catch it.
Umpire says no bat involved. England choose to review it.
Need 133 off 36 balls
A maiden from Moeen Ali to new batter Taijul Islam. England are all but there.
Need 133 off 42 balls

England and Sam Curran won't mind that too much I reckon though. The plan is full and straight. You miss, I hit.
Need 138 off 46 balls
Sam Curran, who took three wickets in five overs at the start of the innings, is finally back into the attack.
Taskin launches him through the covers for four before knocking a single to move to a joint-career-high ODI score of 17 not out.
Need 143 off 48 balls
