Harry Gurney has praised Peter Moores for creating a "positive environment" in the England dressing room.
The left-arm seamer (2-20) made an impressive home debut in 50-over cricket in England's 81-run victory over Sri Lanka in the first ODI at The Oval on Thursday and says the one-day squad is playing with confidence.
"Peter is a coach who sends you out there with confidence," Gurney told Sky Sports.
"He wants players - particularly someone like me who was coming in on debut - to come in to the team and do what I have done to get myself here and that's hopefully something I've taken out on to the pitch and have done.
"It's a really positive environment. To be fair, when I joined up with the team in the West Indies just after Australia, the atmosphere was really positive even then, so now under a new coaching setup and some new playing personnel, the atmosphere is absolutely brilliant, despite what happened in the winter."
Gurney has enjoyed the start to his international career, having been an unused tourist in the tour of the West Indies in March before making his bow against Scotland in Aberdeen.
"It's been a bit of a whirlwind really. I was on the periphery for a little while," he said.
"I went to the West Indies (in March) and it was frustrating not to play, so to finally get my opportunity and go out there with the Three Lions on my chest is an amazing feeling and one that I want to continue for as long as I can.
"After winning the first ODI, we'll be looking to perform as consistently with bat and ball and if we do that we'll come out as series winners at the end of it."
Gurney has aspirations of breaking into the England Test team, knowing his left-arm seam would offer Alastair Cook more variety to his bowling attack.
"My red ball game is a work in progress," he added. "I'm a little more consistent and rounded as a performer with the white ball, but I'm getting better and better with the red ball and I offer something a little bit different, so who knows."
England have confirmed they will release Tim Bresnan to play for Yorkshire in the Roses match at Headingley, starting on Sunday, if they do not select him to play in Chester-le-Street.
Alex Hales has been added to the England squad as cover for Cook, who has right groin tightness. Cook will be assessed ahead of Sunday's game.
