Chelsea have endured a nightmare start to the season... Sportsmail pinpoints the 20 damning statistics showing how the campaign has gone so horribly wrong

• e-mail

From confetti and fireworks in May, to frowns and groans in November, it's been quite a turnaround in fortunes for Chelsea.

Having romped to the Premier League title with an eight-point margin over Manchester City last season, Stamford Bridge has since become a stagnant home for Jose Mourinho's men, with the team floundering in 15th position, with 11 points from 11 games played.

With Chelsea also out of the Capital One Cup and having taken just four points from three games in Group G of the Champions League, Sportsmail pinpoints the 20 damning statistics that prove why it's more blue than ever at the Bridge.

Chelsea manager Jose Mourinho speaks with his staff after his team's 3-1 loss to Liverpool on Saturday

1. Manager Mourinho has lost six Premier League matches this season – he's never lost more in a league campaign at Chelsea; he lost six in the entirety of the 2013-2014 season.

2. And it's not been much better in the cups for the Blues, with nine defeats in their first 17 games this season in all competitions; they lost only three of their first 52 last term.

3. This is Chelsea's worst points tally in a league season after 11 games (11), surpassing their previous low of 13 in both 1992-93 and 1993-94.

4. It is also the Blues' worst defensive performance after 11 games of a single Premier League season (22 goals conceded); Chelsea have already let in more goals this campaign than they managed in the whole of 2004-05 (15) and the same number as in 2005-06.

Chelsea, led by captain John Terry, have conceded 22 goals in 11 Premier League games this term

5. Of all reigning Premier League champions, this is the worst title defence after 11 games of a season - previously it was Blackburn Rovers' tally of only 14 points in 1995-96.

6. Chelsea have the same number of points (11) after 11 games this term as they managed in their first six games of 2007-08, when Mourinho was sacked.

7. At this stage last season, Chelsea had 29 points; 18 more than they currently have. Chelsea won't be able to reach this tally until their 17th game at least – that's if they win their next six games in a row. 

8. Mourinho has lost seven of his last 13 league games as a manager. He had lost seven of 70 league matches as boss prior to the current run.

9. The highest position that a side has achieved after earning 11 points from their opening 11 games of a Premier League season is sixth (Aston Villa in 2003-04).

10. Only Sunderland (69) have allowed their opponents more shots on target in the Premier League this campaign than Chelsea (63).

11. Chelsea have conceded at least two goals nine times in their first 11 league games. They did so only twice throughout Mourinho's first term at the club in 2004-05.

12. The decline of Eden Hazard: After the same amount of Premier League games played last season he had scored three goals as opposed to zero this term, and his passing accuracy was 89.5 per cent, compared with 86.1 per cent.

13. The team's joint-top league scorers Diego Costa, Willian and Ramires have just two goals each. Spain striker Costa had 10 at this point last season.

14. Chelsea's goal difference from the past 22 league matches is zero. In comparison they had plus 26 in their previous 22.

15. The Blues were knocked out of the Capital One Cup to Stoke City in this year's last-16 round; in their last campaign they won the trophy, beating Tottenham Hotspur 2-0 in the March 1 final earlier this year.

16. Chelsea have picked up just four points from three games in Group G of the Champions League this season. They sailed through the group stages with 14 points last year, before being knocked out on away goals by Paris Saint-Germain over two legs in the round of 16.

17. In an increasingly disastrous season, Chelsea's discipline has been particularly poor since August. The club's players have so far picked up three red cards and 29 cautions in the three competitions they have been in this term.

18. And Mourinho has also let his frustration get the better of him this campaign. He was fined £50,000 and handed a one-match suspended stadium ban, after accepting a misconduct charge from the FA for comments made to Sky Sports after Chelsea's 3-1 defeat by Southampton, before being sent off at half-time during his side's 2-1 away loss to West Ham United.

19. Eight points have been dropped by Chelsea after being in front in games, with only bottom club Aston Villa throwing away the same amount so far. Bournemouth, Newcastle United and Southampton come closest to Chelsea and Villa with seven points dropped from winning positions this season, and Liverpool and West Brom have both relinquished six.

20. Chelsea lost their first game against Liverpool in seven Premier League meetings this weekend, having won three and drawn three previously.
