Former left-arm spinner and current director of cricket Ashley Giles is confident England will have a new head coach before the tour of New Zealand in October. 

Giles said ECB has begun the search for Trevor Bayliss' successor "in earnest" now that the gruelling home summer is over and a list of candidates is expected to be rectified next month. 

"In terms of process, it has started in earnest," Giles told reporters at Lord's. "There are a lot of candidates out there and, at the moment, I'm going through the process of trying to gather some interest from parties but then have some longer telephone calls with these guys or face-to-faces until we get to a point where we can put together a shortlist. There are some strong candidates out there."

"There's some internal, there's some English and there's some very good overseas. I'm looking forward to it and it's my first appointment because it's my first major one."

Despite talks of it, Giles confirmed England isn't considering the option of split coaches for red and white-ball formats having experienced the perks of it himself at the helm of backroom staff for ODIs and T20Is from 2012 until 2014 when Andy Flower was in charge of the Test side. 

"I understand the chat around split coaches and it's not only because of my experiences," Giles, though, explained. "With two head coaches, we've got a group of players playing across formats."

"One might be a really mature experienced coach - one younger, less. One form's flying, one's not. There's a pull over Stokes: 'Is he going to be rested this T20 series or not?' There's a lot of conflict there straightaway."

"Suddenly because this team's winning, they like this bloke a bit more and it might be nothing more than they're just winning. There are a number of things there that are going to give me a headache quite quickly."

"Having the one voice is important, but accepting that one voice is going to need some time away. And if you've got three very good assistants, it's an opportunity to develop them as leaders. It's a consistent voice for sorts because the players will know them. That's how I see it," he concluded.
