Chris Powell hopes Derby County can emulate his ex-club Leicester City's achievements as the East Midlands duo prepare for Friday's FA Cup meeting.
Shock 2015-16 Premier League winners City also have a Champions League last-16 tie with Sevilla on the horizon.
Rams assistant boss Powell told BBC Radio Derby: "The season they had was quite unique, it won't happen again.
"They're now having their Champions League excursion and that's something we aspire to."
Powell, who reached the quarter-finals of the FA Cup as a Derby player in 1997, ended his career with Leicester in 2010, before briefly being part of the Foxes' coaching staff.
