Marcus Trescothick hopes England's first victory in six Twenty20 matches will act as a launch-pad for their limited overs fortunes.
England held their nerve to defend a total of 165-6 and secure a five-run win over the West Indies, the defending ICC World Twenty20 champions, in Barbados.
Although the tourists still lost the series 2-1, former opener Trescothick told Sky Sports there are signs England - who beat the West Indies 2-1 in the preceding 50-over series - are getting back on track after a disastrous winter in Australia.
"The game ebbed and flowed the whole way - England had it won, then the West Indies clawed their way back in," he reflected. "It was a great game; that's what you want to see in Twenty20 cricket.
"England will take confidence from this. The rebuilding process from the winter will take a little bit of time given the change of management, with Ashley Giles, Paul Collingwood and Graham Thorpe involved.
"As we saw with Australia during last summer's Ashes, it takes that little bit of time to rebuild and this could be their process at the moment. We might see England really kick on in their one-day cricket."
Openers Alex Hales (38 off 31) and Michael Lumb (63 off 40 balls) set the platform for England's victory, scoring an impressive 64 off the six powerplay overs before improving their first-wicket stand to 98 off 11.5 overs before Sheldon Cottrell (2-37) broke through.
"It was a great start and it really took the pressure off," said Trescothick. "Hales and Lumb looked more positive, more relaxed. The second over went for 17 and once they got that under their belt it was a lot easier to perform.
"I'm delighted for Michael Lumb because he really needed a score at the top of the order and to go about it in that fashion - to be aggressive, hit boundaries and back himself against all bowlers - was perfect for what they wanted.
"England probably won't face much seam in the first six overs of their innings at the World T20 so it will be interesting to see if that changes anything; but Lumb is a good enough player and hopefully he can take this on and keep doing the job."
However, from 96-0 off 10 overs England's innings faltered as they scored only 43 for the loss of six wickets in the next nine overs.
Only some last over fireworks from Barbados-born all-rounder Chris Jordan playing for England in front of his friends and family enabled England to post a challenging total.
Jordan blasted 27 not out off nine balls, striking Dwayne Bravo for four sixes, before taking 3-39 in four overs to tilt the game in England's favour and claim the man-of-the-match award.
"That final over was absolutely vital, otherwise England would have been 20 runs short," said Trescothick. "Chris Jordan has had a great game with runs, wickets and catches.
"While he was at Surrey his career was a little bit up and down and he wasn't getting the opportunity that he needed but he's flourished since moving to Sussex. He's had a good role to play with the ball and he's fitted in nicely.
"I don't think Jordan will feature once we get to Bangladesh. It's a wonder if they actually get Stuart Broad, Tim Bresnan and Jade Dernbach in the side anyway when Ravi Bopara could bowl a few overs and they could play two spinners plus Moeen Ali.
"But judging Jordan on this performance, he's given himself a really good chance."
Despite the defeat, Sky Sports guest Kieron Pollard - who will be prevented from defending the title he helped the West Indies to win in 2012 by injury - said his team-mates are well-set going into this year's tournament.
"At the end of the day this was a game of cricket and they want to win but they have a fair idea of who they want to select and what they want to do in the World T20 - and they look strong; they look like they have every base covered and it's just a matter of turning that into performances when they go to Bangladesh," said Pollard.
"There are a few 'one per centers' they can brush up on. A couple of times the bowlers could have got back to the wickets and they still need to be more consistent when they are bowling and you want to finish off the innings well, as well.
"England still need to work at their batting when pace is taken off the ball and being able to hit the spinners over the boundaries. Chris Jordan came in for the last over and hit four sixes; there were only four sixes in the 19 overs before that from the other guys."
