Stuart Broad is calling on England to find new match-winners in an improved atmosphere as they move on from Kevin Pietersen.

Broad flew on Thursday with his ICC World Twenty20 hopefuls for a short tour of the Caribbean, a chance for his young team to test themselves against the tournament holders on their home soil before this spring's main event in Bangladesh.

The captain knows that a share of victories in three initial one-day internationals in Antigua - and even more importantly three Twenty20s in Barbados - are a must after the Ashes whitewash which hastened the end of record run-scorer Pietersen's England career.

Broad reflected at his Gatwick departure press conference on a winter of "disaster" and "heartbreak", yet is confident England can get back on track.

Team director Andy Flower, who resigned, and then Pietersen - axed by the England and Wales Cricket Board - have left the fold since the 2013/14 Ashes humiliation.

An ECB statement later clarified an issue of "trust" as a key component of England's future without Pietersen.

Broad had no major input as telling calls were made on the management and playing personnel who will try to take England forward.

"I was aware of discussions towards the end of the Australia tour, but (I was) not deeply involved particularly," he said.

"It was a decision made by guys that have the English cricket team at their heart, and they want the team to improve.

"The guys that made the decision are very keen for English cricket to move forward.

"There's no egos involved in making decisions like this. It's about improving performances on the field and atmospheres off it."

Pietersen was named player of the tournament in the Caribbean when England won what is still their only global trophy to date, at the 2010 ICC World Twenty20.

Broad said: "I have fond memories of KP from 2010, when he was the kingpin in helping us win that 'World Cup'.

"There's no doubt Kev was a fantastic player for England, part of a hugely successful era.

"But it's time for the guys in that changing room to realise they can be match-winners and can step up, now."

England appear to have chosen harmony, in which they hope rising stars such as Jos Buttler and Ben Stokes can flourish, over Pietersen's game-changing abilities.

"The decision was taken from guys who were desperate for England to improve in the future, not just in the next four or five months," Broad added.

"We do have to make improvements - that's obvious.

"It was heartbreaking to lose 5-0, and we lost a lot of good men in doing that.

"It's a winter that was a disaster, but as an England side we have to look forward now.

"We can't dwell on it.

"All I can focus on is this trip now."

England followed their Ashes whitewash with defeat too in back-to-back ODI and Twenty20 series in Australia.

Limited-overs coach Ashley Giles was in charge then and will be in the West Indies and Bangladesh, where he will also have Paul Collingwood - England captain for that 2010 triumph - on board as his assistant.

Whether Giles' tenure is extended to the portfolio Flower previously held, or comes to an end, will surely depend on the team's fortunes over the next six weeks.

Broad knows there is no time to ease into a transition period.

"It's very important we start winning again," he said.

"We've obviously got a fantastic opportunity to start [doing that] for England again.

"In the sub-continent, our skills haven't been up to scratch. (We need) to work on playing spin, and the Caribbean will be good for that.

"The players are excited about the chance of winning games, because it's been a while.

"When you've lost so many games over the last six months, it hurts.

"We've got to move on. It's very important we don't sit in the past, because if we do we'll never improve."

Whatever the dressing-room dynamic, scoreboard currency as ever will underpin success or otherwise in the post-Pietersen era.

"We know the team atmosphere is important, but also you still need people to score runs and take wickets," Broad added.

"It's a fine balance.

"I think it's obvious that we struggled in the winter, and changes had to be made."

Self-belief and a responsibility to put things right will be the tenets of motivation in Broad's squad.

"Twenty20 is about match-winners and taking the game by the scruff of the neck, so that's the challenge for this young group now," he said.

"There's no doubt the players let Andy Flower down this winter.

"The coach can only do so much.

"We let the coaches down this winter, and it's up to the players to respond and perform."
