Eoin Morgan is determined to continue the culture change which has transformed England's limited-overs cricket.
It is barely more than 12 months since England, washed up after their miserable early exit from the 2015 World Cup, reported back for duty at Edgbaston to take on New Zealand.

At the start of that high-octane five-match Royal London Series, they responded with a record total of 408 for nine - on the back of hundreds from Joe Root and Jos Buttler.
It is a measure of Buttler's brilliance that his century that day is only the third-quickest on his, and England's, CV.
Nonetheless, it helped raise the bar for Morgan's team - who went on to beat the Kiwis 3-2.

They have since lost to Australia at home and South Africa away by the same margin, in between beat Pakistan 3-1 in the United Arab Emirates, and then reached the final of the ICC World Twenty20 in India.
A proactive approach has been the constant, several times threatening that national-record total.
There was also a wonderful run chase against New Zealand, including Morgan's last ODI hundred, at Trent Bridge - venue for this summer's first Royal London match against Sri Lanka on Tuesday.
The captain is adamant the progress begun a year ago, and sustained so far since, will not be allowed to stall.
"I don't think it will be lost," said the Irishman. "We're trying to change the mentality.
"The [old] mentality is that if you're getting beaten around the park, you try and bowl tight and move things around - but actually trying to get the batsman out is still a priority.
"The same with the bat, if we're three down and you get presented with a half-volley, you still do it.
"It's part and parcel of changing the mindset of the side."
The self-belief from England's run to the Twenty20 final in Kolkata can surely only help.
"I don't know if it's a springboard, but it's certainly a huge confidence booster," said Morgan.
"This is a key summer in that we're 12 months down the road, and we have built a lot of confidence.
"There's a bit more expectation on us as a side, and it's important to relish that expectation."
This is no time to stop and stare, with a Champions Trophy in this country next summer and then a home World Cup two years later.
Morgan said: "I'd like to think that, having put in performances like that, we can reconnect with that as a side.
"Given conditions and opportunity, we could do similar - potentially.
"The attitude we showed in all the games, whether we were under the pump or on top, was very important."
There are transient issues for England nonetheless, beginning with the difficult task of replacing the injured Ben Stokes against Sri Lanka and the slightly easier one of working out how to find room for the in-form Jonny Bairstow to return for his first ODI since the end of last summer.
"Ben leaves a huge hole," said Morgan, who cannot help but be impressed with Bairstow's prolific run of scores over the past 12 months.
"Jonny has been in an incredible run of form for a very long time, the snippets we have seen in one-day cricket have been priceless.
"He came in during that New Zealand series and won us the game. He thoroughly deserves to be selected in the squad.
"The runs he has scored in Test cricket and county cricket have been so many it is actually a joke."
Still, accommodating Bairstow and Buttler in the same Stokes-less team - the former without his Test match wicketkeeping gloves - means something will have to give in England's bowling resources.
"The Ben Stokes conundrum does [give us] a couple of problems," said the captain. "Either way, we have to be comfortable with what we go with."
Morgan acknowledges he also has an issue to address when it comes to his own recent productivity.
"The last [ODI] 50 I scored was the first game in the UAE," he said.
"You forget your nuts and bolts that hold things together.
"The South African series was more that I didn't get going, a rhythm thing.
"I feel a lot better than I did in the winter, so I hope on home soil I can get a score under my belt."
Collectively meanwhile, England are 10-2 up in the inaugural Super Series - Andrew Strauss' brainchild to pep up bilateral series across the formats.
Not yet top of Morgan's agenda, he does see merit in the initiative.
"It is not a complication," he added. "The Test guys did an incredible job, and it is up to us now to concentrate on winning games of cricket.
"[The Super Series] is not massively at the forefront of our thinking, but we will be rewarded if we do have some success."
