Eddie Jones says Leicester's post-title slump is a lesson to his unbeaten England side on the work required to stay at the top.
Jones' Six Nations holders are on course to become the first back-to-back Grand Slam winners since 1998 after two victories in this year's tournament.
Next up is Sunday's home game with Italy, which comes at the end of a week that saw Claudio Ranieri sacked just nine months after leading 5000-1 shot Leicester to the Premier League.
Jones, who welcomed Chelsea boss Antonio Conte to Pennyhill Park in the run-up to the Italy match, has warned his England players even a side on a 16-match winning run can be vulnerable to collapse.
He told Sky Sports News HQ: "It's just an example of how diligent you have to be when you're successful.
"If you turn a blind eye to certain things, or allow certain things to happen, then people start taking shortcuts. And as soon as you start taking shortcuts things multiply."
Jones sympathised with Ranieri paying the price "as managers generally do" for a deterioration in results which could be down to a number of factors.
And the Australian predicted a future for rugby that includes the kind of unsentimental dismissal that cost the Italian his job.
"It's going to come in rugby as the game gets more professional," he said. "It's still a young sport, but the pressure to win and make changes will become more exact."
Ranieri's compatriot Conte is in no immediate danger of the sack with his Chelsea side sitting eight points clear at the top of the table, and Jones took the chance to tap into the Blues boss' knowledge when they met.
He said: "The process he went through to develop Chelsea from a dysfunctional team to a great winning team was quite enlightening. It's always great to meet coaches like him."
