New assistant coach Lee Blackett says he had licence to remould England's attack during this summer's successful audition for a permanent role.
Bath attack coach Blackett was seconded to Steve Borthwick's side for two Tests against Argentina and a one-off match against the United States.
England, who were without 15 players who toured with the British and Irish Lions, won all three matches, scoring 13 tries in the process.
"Steve said from the outset that, while we obviously have to carry over some stuff, the attack must also be a true reflection of what Lee Blackett wants," Blackett told BBC's Rugby Union Weekly.
"I took a lot of confidence from that - he is backing you as a coach to come in and deliver and there is a reason why he wants you to join the environment."
Blackett will link up with England full-time at the end of September after the Rugby Football Union reached an agreement to buy out his contract at The Rec.
