Rugby Football Union (RFU) chief executive Ian Ritchie has stressed that the new England head coach must have international experience and said money will be no object when appointing Stuart Lancaster's successor.
It was announced on Wednesday that Lancaster's three-year reign had come to end following a review into England's failure at the Rugby World Cup on home soil.
The 46-year-old left his role by mutual consent after England became the first host nation to fail to qualify for the quarter-finals of a World Cup, losing to Wales and Australia in Pool A.
Ritchie confirmed that Lancaster has left the RFU, but his assistants Graham Rowntree, Mike Catt and Andy Farrell remain under contract.
Michael Cheika and Eddie Jones are among the coaches to be linked with the vacancy and Ritchie confirmed that only candidates with international pedigree will be considered, but did not pick out specific contenders.
Ritchie said at a media conference: "We now need to look to the future.
"It is very important we get a person of proven international experience. While this is a priority, it is important we take sufficient time to find the right person.
"I think this is a very attractive job in world rugby. Speed is important (in making an appointment), but getting the right person is the main thing.
"You need to get the best possible coach, this is not a matter of financial implications, it's a matter of getting the best possible coach for English rugby and we will do that without any inhibitions."
Ritchie took his share of the blame for England's poor showing in the World Cup but insisted it is time to look forward.
He added: "I don't duck the accountability and responsibility. If you're the chief executive of an organisation you have to deal with that but it's important we move on."
