Bundesliga Week 19: Klopp and Dortmund still can't win

So with the Bundesliga winter break over its back to the action and Borussia Dortmund are still nailed to the bottom of the table after losing at home to Augsburg.
Just rubbing that bit of salt into the wounds for Dortmund fans is Bayern's dominant position atop the table.

I had a quick look at Dortmund's situation back in week 13 and at the time it was a case of a dominant shots team being hammered by a nightmare inducing PDO score. And the PDO problems were at both ends of the pitch - both their shooting and save percentage were around 10 points lower than the league average.
PDO is an interesting tool as it helps spot trends that are not necessarily within the team's control and is often used as a proxy for luck - 100 being the average, below = bad luck, above = good luck.
And, certainly over a large enough sample size (and in ice hockey where its been most effectively used) it regresses towards 100 over time.

Let's have a look at Dortmund's (and the rest of the leagues') stats now.

Amazingly, Dortmund's "luck" appears to have got worse since week 13, not better.
As you'll see below, I actually had to extend my graph below its normal PDO low point to accommodate them.
(And apologies for stretching the graph in the other direction, but I thought I really should put Bayern on it this time around.)
But perhaps what is most interesting about Dortmund's situation, is they've become MORE dominant at getting shots on target since week 13. The overall shots share score (Corsi/TSR) is basically unchanged, but the SoT share has gone up by 0.03 (or 3% points). That's a really big improvement over such a short space of time and shows just how damning this PDO run is.

It is possible that some of Jurgen Klopp's tactics are playing into this problem (this is a harder state to test), but Dortmund certainly appear snake-bitten defensively, as WhoScored suggested:

Borussia Dortmund: Have committed more errors that have led to an opposition goal than any other team in the Bundesliga this season (10)
— WhoScored.com (@WhoScored) February 4, 2015

I wouldn't go so far as to say calls for Klopp to go are complete madness, but from this initial analysis, it certainly seems a horrible run of misfortune at both ends of the pitch.

Usually when I have to extend for both Bayern Munich and Borussia Dortmund it would be for the same positive reason, in this case it is anything but.

Bundesliga Week 13: What's wrong with Borussia Dortmund?

A slight digression from the football league for just one post this week.

Possibly the biggest story in European football this weekend was Borussia Dortmund’s fall to bottom of the Bundesliga.
Given the team’s massive support, substantial recent success and as being one of the few real challengers to Bayern Munich over recent years, it is not surprising this has been big news.
This is even more so with Jurgen Klopp’s high profile and rumours of interest from Premier League clubs.
All of that has led to some rather strong (almost gleeful) attacks at Klopp and his reputation.

So here’s the Bundesliga table, not very pretty reading for Dortmund fans:

Position	Team	Played	Won	Drawn	Lost	Goals For	Goals Against	Goal Difference	Points
1	Bayern Munich	13	10	3	0	32	3	29	33
2	Wolfsburg	13	8	2	3	25	12	13	26
3	Leverkusen	13	6	5	2	25	17	8	23
4	Augsburg	13	7	0	6	18	13	5	21
5	M'gladbach	13	5	5	3	16	10	6	20
6	Schalke 04	13	6	2	5	21	18	3	20
7	Hoffenheim	13	5	5	3	21	21	0	20
8	Hannover	13	6	1	6	13	18	-5	19
9	Ein Frankfurt	13	5	3	5	22	24	-2	18
10	Mainz	13	3	7	3	16	18	-2	16
11	Paderborn	13	4	4	5	18	22	-4	16
12	FC Koln	13	4	3	6	13	18	-5	15
13	Hertha	13	4	2	7	17	23	-6	14
14	Werder Bremen	13	3	4	6	18	26	-8	13
15	Freiburg	13	2	6	5	14	20	-6	12
16	Stuttgart	13	3	3	7	18	27	-9	12
17	Hamburg	13	3	3	7	7	17	-10	12
18	Dortmund	13	3	2	8	14	21	-7	11

But let’s have a look at the underlying stats to see if we can pick out anything that’s going wrong at Dortmund.

Can anyone spot the problem?
(Incidentally, this graph was plotted on my standard dimensions for this and so dominant have Bayern been that they don’t fit on it in EITHER direction!)

So yeah, Dortmund’s PDO is so low they barely fit on the graph. It's just brutal.
I’ve not really seen much of Dortmund this season, so can’t comment too much on whether this is a systems thing of just sheer bad luck, but it’s highly unlikely that the PDO stays THIS low for the rest of the season.
Given how dominant Dortmund are in terms of shots, Klopp's assessment that it’s pretty well governed by bad luck is fairly pragmatic, even sensible, approach to take.

Being a smaller league and shorter season though means teams are much more vulnerable to being devastated by short term slumps like this over the course of a season.
Dortmund’s title hopes are (one would imagine) pretty much shot now, but if they get a rebound of PDO as strong as the fall has been and they could yet challenge for a Champions League spot.
The rest of their underlying numbers are good enough – a sparkling shot share (Corsi/TSR) of 64.4% (third behind Bayern’s 72.7% and Leverkusen’s 69.2%) is testament to that.


The problem is that current second place team Wolfsberg are doing a pretty tidy job themselves too. If they can make up the 12 point gap on Leverkusen in third that would be a remarkable end to the season – though Klopp’s employers may just settle for avoiding relegation at the moment.
