The most unpredictable season?

It is the Premier League season that has absolutely everyone scratching their heads.

Champions Chelsea are down in 14th. Leicester, bottom at Christmas final year, are prime significantly less than 12 months later.

In fact, as this image below shows, the old cliche that anybody can beat any person, has by no means been much more apt. Undoubtedly, there have been some strange results.

Graphic showing every team beating each other

But just how uncommon has this season actually been and what have been the important factors in creating it so unpredictable? BBC Sport crunches the numbers to uncover out.

Chelsea go from champions to chumps

Chelsea’s start off to the season is the worst of any reigning Premier League champion.

In reality, Blackburn are the only other side to have picked up fewer than 20 points in the first 15 games of a title defence.

Chelsea and Manchester United have mounted the best starts to a defence, each registering 40 points in 2005-06 and 1993-94 respectively.

Tight at the leading

This is reasonably unusual. There are just six points among prime side Leicester and fifth-placed Tottenham – it is only been that close one other time in the previous ten seasons.

Away the lads

Percentage of away wins in the Premier League

Teams are loving an away day this season.

There have been 51 away victories from 150 Premier League games this term – that is 34% of fixtures.

Of the 9,130 games in Premier League history, 27.25% have ended with a win for the visitors.

New boys bucking the trend?

Promoted teams picture

The three promoted teams of Bournemouth, Watford and Norwich are all at the moment out of the relegation zone, which you may think is uncommon.

Lately, it’s not been that uncommon.

In truth, it has happened twice in the preceding five seasons. Newcastle United, West Brom and Blackpool had been above the drop zone at this point in 2010-11, as had been QPR, Norwich and Swansea in 2011-12.

Even so, these are the only 3 occasions the feat has occurred in the previous decade, and rarely do a single of these sides beat the champions, as Bournemouth did when winning 1- at Chelsea on Saturday.

Will Leicester win the league?

The team that is best in early December is most most likely to go on to claim the title, right?

If history is any indicator, Leicester City have truly got practically a 50-50 opportunity of causing a enormous shock and becoming champions.

Exactly where does the team top soon after 15 games finish?

?

In Premier League history, the team prime after 15 games has gone on to win the title 47.8% of the time. And that rises to 72.7% more than the previous 11 seasons.

Manchester United have been leading following 15 games eight instances – and have converted that into a title on six occasions

But of the eight distinct clubs to be prime at this stage, only three – Manchester United, Manchester City and Chelsea – have gone on to win the title.

Or is it exact same old, exact same old?

It’s all really intriguing, but then once again, a fast comparison of the table this year with how it ended last season suggests tiny has changed.

Current top six

Four of the current best six completed in the best six last season…

Last season's top six

And the existing bottom three…

Current bottom three

Effectively they all just about survived final season…

Last season's three to avoid the drop

And even in mid-table…

Current mid-table

There’s a familiar appear to how it finished up final term, with 4 of the same six teams occupying the middle six positions.

Last season's mid-table

So maybe the world of the Premier League hasn’t been totally turned upside down just yet.
