The Foxes will be looking to lift their first FA Cup on Saturday against eight-time winners Chelsea, but 21 years ago, Leicester were flying high at the top of the Premier League standings.
Before we face the Blues in the capital, here's one of our favourite past encounters...
Chelsea 0 Leicester City 2
Sunday 17 September, 2000
Premier League
Stamford Bridge
Unbeaten Leicester City made it four wins from six at the start of the 2000/2001 season with a 2-0 success over Chelsea at Stamford Bridge which nudged them closer to the Premier League summit.
Following the departure of popular manager Martin O'Neill, to join Scottish side Celtic in the summer, the Football Club appointed Gillingham's Peter Taylor to replace the Northern Irishman at Filbert Street.
City headed to west London on Sunday 17 September to tackle managerless Chelsea following victories over West Ham United, Ipswich Town and Southampton as Taylor's men started the season brightly.
After Gianluca Vialli left Chelsea, Graeme Rix and Ray Wilkins took temporary charge, while new Blues manager, Claudio Ranieri watched from the stands 16 years before earning legendary status in Leicester.
Amid a hostile atmosphere, which included the home crowd often chanting Vialli's name, the Foxes were ahead inside just eight minutes as Neil Lennon crossed for Muzzy Izzet to head past Carlo Cudicini.
After 34 minutes, Chelsea icon Gianfranco Zola played it in for Dennis Wise, who attempted to curl the ball in from 20 yards out, only to see it easily gathered by Tim Flowers, who would later win September's Player of the Month.
In the second half, meanwhile, Roberto Di Matteo hit a fearsome half-volley, which Leicester's 'keeper needed to acrobatically tip it round the post in order to maintain his side's slender lead in the capital.
While Matt Elliott missed a big opportunity to double City's lead, with the Scotland international's header drifting agonisingly wide, the visitors were able to seal all three points in the latter moments.
Stan Collymore, who had earlier replaced Darren Eadie from the bench, skipped into the penalty area to apply a deft flick to a characteristically pin-point Steve Guppy cross in the 82nd minute.
It ultimately sealed a wonderful 2-0 win for Leicester and continued their impressive start to the 2000/2001 campaign. Successive draws against Everton, at home, and Sunderland, away, followed.
Those two points were enough to nudge City to the top of the Premier League standings, one point clear of Manchester United after eight matches, earning Taylor the top-flight Manager of the Month Prize.
