Chelsea, on the other hand, suffered a shock 0-1 home defeat to Bournemouth – their fourth home defeat of the campaign – to leave them in 14th and just three points above the drop zone.
It has been an incredible turn of events, and one which is all the more astonishing considering their respective positions at the very same point in last season’s campaign.
Jose Mourinho’s men won the 2014/15 Premier League title at a canter, and there was even talk about them matching Arsenal’s record of going through the entire league campaign unbeaten.
That’s because after 15 games last season, Chelsea had 36 points and saw their 14-game unbeaten run come to an end with a 2-1 defeat at Newcastle United. Still, they were clear by this point.
Leicester, in contrast, looked in real danger of going down as they picked up just ten points from their opening 15 matches – leaving them a whopping 26 points behind the then league leaders.
17 - After 15 games last season, Chelsea were 26 points ahead of Leicester - they now find themselves 17 behind. Swing.— OptaJoe (@OptaJoe) December 5, 2015
Fast forward one year, and Chelsea are now 17 points behind the Foxes – a swing of 43 points. It’s an incredible turnaround from both clubs, and one which has been entirely unexpected.
The Blues were rightfully regarded as favourites to regain the title last summer, whereas many observers saw the appointment of Claudio Ranieri as a potential gamble which would see Leicester go down.
But the Italian coach has been nothing short of fantastic this season, and with nobody seemingly wanting to grab the initiative in the title race, Leicester now find themselves challenging.
The Foxes have a spirited defence, an excellent midfield and goals galore in the likes of Jamie Vardy and Riyad Mahrez – a combination which could just see them achieve the unthinkable come next May.
