The England international moved from non-League Fleetwood to Leicester in 2012 for £1 million and went on to win the Premier League four years later.
Fleetwood host the Foxes in an FA Cup third round game on Saturday, though Vardy is unlikely to play due to a groin injury.
"The way he's playing, you're not finding that sort of player very often anymore," Rosler said.
"I think for the club that we are and our DNA, Jamie is the perfect inspiration for our young players, to try to emulate his career and his way is what we are about.
"We are a football club that wants to produce results but we also have a clear business model that we develop young players and hopefully sell them on.
"I have never worked with Jamie but obviously the way he plays he is right up my street.
"To have someone who plays so wholeheartedly, with such a directness, with such a running ability and goal-scoring ability would be very nice to have in a team."
