England: Ashley Giles happy to make tough coaching decisions
Ashley Giles says he is not frightened to make tough decisions if he is appointed as England's head coach.
Giles, limited-overs coach since 2012, claims he can make difficult calls despite his "nice guy" reputation.
"I led Warwickshire for five years and had to make some tough decisions and made them," Giles told BBC Sport.
"There's been a lot said about my style of coaching, whether I'm tough enough and can make those strong decisions.
"If I don't make those tough calls, people above me will make those judgements on me."
England can no longer qualify for the semi-finals of the World Twenty20 after a three-run defeat by South Africa on Saturday.
But Giles, 40, believes there have been encouraging signs during the tournament.
England, who face Netherlands in a dead rubber in Chittagong on Monday, beat Sri Lanka in dramatic fashion thanks largely to Alex Hales's unbeaten century.
"It's disappointing to be knocked out and that will hurt everyone in the team. But I think there have been some positives," Giles said.
"The guys have gone out and expressed themselves, played fearless cricket, and that's all we have asked of them."
Giles also thinks England need to review how they use players who play all formats of the game.
"With a World Cup coming up, recently perhaps one-day cricket has suffered more than Tests," Giles added.
"We'll have to look at that balance again, and I think it's important we put our best sides out as much as we can."
