Ennis' triumphant summer might have come in the capital but her heptathlon victory was made in the Steel City.
Despite the Games' promise to inspire a generation however the main training facility Ennis uses day-in day-out, the Don Valley Stadium, is bring threatened with demolition.
Sheffield City Council is looking to save £50 million from its 2013-14 budget and has confirmed demolishing the 25,000-seater stadium is an option.
A final decision on the proposal will come in March however Minichiello has hit out at the plans, questioning the juxtaposition between the much-heralded Olympic legacy promises and the closure of facilities.
If Don Valley were to close then, according to Minichiello, Ennis would likely do her track work in Leeds.
"The saddest thing about this is what it says about Olympic legacy," said Minichiello. "Don Valley was where it all began for Jessica and demolishing it means kids in Sheffield will not have the opportunity that Jessica has had."
