The 44-year-old has been promoted from fast bowling coach to replace World Cup-winning Australian Trevor Bayliss, who stepped down as head coach last month at the end of his contract.

"I think (there's a good) relationship between myself and the two captains (Joe Root and Eoin Morgan), and I've got a strong relationship with all the players and backroom staff," he said at his unveiling press conference on Thursday.

"I understand how the system works, how the team works. That continuity is key.

"The step up will bring a lot more responsibility. Not a lot will change, I'll have to step back a little bit but I want (the players) to know I'm available."

Silverwood accepts improving the fortunes of the Test team under Root's captaincy will be his first priority.

"Job number one is helping Joe," added Silverwood.

"We've got a lot of support around Joe, but to keep moving forward so that in two years' time we can go to Australia and make a real impact."

England aim to become the most successful team in international cricket across the various formats and Silverwood continued: "We will become that by building on the white-ball success we've already had - and let's not forget we have two big white-ball tournaments coming up - and moving the Test team forward.

"That means batting a long period of time, building on the success we've had in the bowling and becoming more consistent in winning away from home."

Ashley Giles, managing director of England men's cricket, explained why he labelled Silverwood "the standout candidate" of a coaching search that also saw the likes of former South Africa and India coach Gary Kirsten considered.

"His character, his values, he's a winner - you can only prove that in the environment you're in and he's proven that in the domestic game," said Giles of a man who led Essex to County Championship promotion and then the Division One title.

"The job he did at Essex was fantastic and we're still seeing that legacy now. I think the sign of a good coach is leaving the club better than you found it and that seems to be in evidence.

"The relationship, the knowledge of what we're doing - we've got an exceptional bloke who cares deeply about what we're doing."

Australian Bayliss and Zimbabweans Duncan Fletcher and Andy Flower have had long spells in charge of the England team, with Peter Moores - and Giles in the white-ball teams - the only domestic coaches to hold the role this century.
