Spurs :

1. Number of direct/assisted goals scored has increased by
52/35 % respectively.


Opposition

2. Number of goals scored has increased by 33%


My suggestion for the causes of :

- 1 is due to the overall increase in rate of goals scored

- 2 is that the Spurs defence has been worsening (this measure is a KPI)

- 4 is due to the Spurs attack being more potent

 

Not sure where else to squeeze this in, as that might involve resurrecting a months-dead thread, but there's talk that a couple of our current squad have started taking their coaching badges

Anyone want to make a wild guess at who those players would be, and why one of them is obviously Ben Davies?

Analysis of report R3 (LONG) .

I contend that for any measure M, a value change
of at least 33% suggests that M should be
scrutinised in more detail. So on that basis ...

1. General

Here is the corresponding "season compass" for this point in time :

Pts = 1, GF = 0, GA = +4.


Notable measures :

Spurs

Defence
- clean sheet : -37.5%


Opposition

Attack
-- scored : 35%


So there is a very good match here.
The % drop in clean sheets is corresponding to an increase in
goals conceded (and the effect is seen in the collapse in the
"season compass" from its recent heights at week 10/11) .

If Spurs could keep more clean sheets, the PL campaign would
be far better off.

So what is specifically happening to the defence to prevent this ??

Opposition

Attack
- attempts : 10.5691%
-- on target : 10.9635%
-- blocked : 4.40252%
-- scored : 35%

--- headed : -75%
--- open play : 48.1481%

--- free kick : -1.5 X
---- direct : -50%
---- indirect : -100%

-- corner kick
--- total : -11.9171%
--- scored : 0%


No significant increase in attempts on goal (total or on target) .
No change in defence from corners (which is good as is) .
Not vulnerable to free kicks.
Not vulnerable to headers (actually better this season) .
But the opposition goals from open play is up 48% .

Spurs :

2. No goals have been scored from free kicks


Opposition

3. Number of goals scored has increased by 47%

4. Number of goals scored by headers has decreased by 52%

5. number of goals scored from free kicks is zero

6. Number of red cards accrued has decreased by 68% .



My suggestion for the causes of :

- 1/3 is that the Spurs defence has been worsening (these measures

- 2 is mainly due to allowing Kane to take direct free kicks

- 4/5 is mainly due to the Spurs defence being able to deal with crosses

- 6 is that the Spurs attack is not putting the opposition under
sufficient persistent pressure to draw rash tackles

 

I was having a read of this thread again over lunch and was thinking about this. One source of the lack of clean sheets is errors from the defenders and GK. The PL’s stats say we have made 6, which I believe is the highest in the division, with Lloris alone responsible for 4 of them. The others are one each from Dier and Romero.

Now I don’t know the way they have calculated this metric, but we are clearly suffering from relying on players who play a high risk game (Romero), have always had errors in them (Dier), or who have clearly regressed to a far more error-prone state than usual (Lloris). Plus we do not control games well enough (particularly due to the technical insecurity of our players, partly due to tactical decisions) so that error prone players are being placed under much more pressure. We’re bleeding goals and can hardly buy a clean sheet.

Something has to change.

 

1. Same way I get some of my measures : by watching match footage
and making a decision on that basis.

2. If you are so inclined, you could go thru all the Sky sports match
highlights vid clips to see if the total goals conceded due to what
you deem as errors tallies with the stats you see quoted.

3. Unfortunately you would also have to do the same for all of last
season (to get a reference stat by which to assess 2) .

Notable changes in performance for the season to date (games = 22) .
Measures expressed as a % of the overall 2021-22 per game measures ...


Spurs :

1. Number of red cards accrued has doubled.

2. Number of OG conceded has decreased by 42%


Opposition

3. Number of goals scored by headers has decreased by 56%

4. Number of OG conceded has decreased by 42%

5. Number of red cards accrued has decreased by 71% .



My suggestion for the causes of :

- 1 is due to unnecessary rash tackles

- 2 is due to the opposition making fewer dangerous crosses into the box
where the ball could be deflected in

- 3 is mainly due to the Spurs defence being able to deal wuth crosses

- 4 is due to the opposition conceding zero fluke OG this season

- 5 is that the Spurs attack is not putting thr opposition under
sufficient persistent pressure to draw rash tackles

Spurs :

1. Number of goals conceded has increased by 44%

2. Number of goals conceded is only 5 less in total than for all
of last season


My suggestion for the causes of :

- 1/2 is due to sitting too deep in defence, and not contesting the space
in CM with the opposition
