Wes Morgan's first goal of the season earned Claudio Ranieri's side their latest a 1-0 victory over Southampton on Sunday to move them seven points clear at the top of the Premier League.
The Foxes captain rose highest on 38 minutes to head Christian Fuchs' cross home meaning they need four more wins to seal a maiden top-flight crown in this most astonishing of seasons.
With closest competitors Tottenham Hotspur dropping two points at Liverpool the day before, the Foxes knew they could open up a significant gap at the summit and they did just that.
Many pundits and fans of rival clubs have been waiting for and expecting the wheels to come off for a side tipped for relegation by most during pre-season.
'It has to be one of the greatest achievements ever witnessed'
But former Liverpool star Michael Owen believes Sunday's win has all but sealed the title for Leicester.
And it is an achievement he ranks higher than rivals Forest's back-to-back European Cups in 1979 and 1980.
"I think the title was decided this weekend," Owen said on his Twitter account.
"Virtually every 'expert' including me predicted Leicester to go down eight months ago. Take a bow.
"Has to be one of the greatest achievements football has ever witnessed. I so hope they finish the job now."
When it was put to Owen about Forest's European Cup double, the former Real Madrid striker said: "That is the only achievement in living memory that comes close to what Leicester are doing right now."

Does it really trump Clough's Miracle Men?
Brian Clough's 'Miracle Men' are widely considered to have pulled off the most astonishing feat in the history of English football when they beat Malmö 1–0 in Munich's Olympiastadion in 1979 and retained the trophy a year later by beating Hamburg 1–0 in Madrid.
If that achievement was not great enough, it was made even more extraordinary by the fact Forest had only won promotion to the top division at the end of the 1976/77 season after finishing third in the Second Division.
From there Clough's famous side became one of the few teams (and the most recent team to date) to win the English First Division Championship a year after winning promotion from the English Second Division (1977/78).
Leicester's place at Europe's top table next season is already secured, whether they could match their great rivals' achievements on that stage remains to be seen.
