Scatter graphics: Serie A, 18 Jan 2016

faHere are updated scatter graphics for Serie A, which compare the attacking and defensive performance of each club. These are explained here if you haven’t seen them before and you can see the previous set here.

Shot dominance

First of all, here is how the number of shots taken by each club compares with those they face in return. The average number of shots taken per match is on the horizontal and the average number faced is on the vertical, so bottom right (take plenty, allow few in return) is good while top left (take few, allow plenty) is bad. The stripes are like contours: the greener the stripe, the better the performance (and vice versa for red).

2016-01-18 I1 Att DefThree of the current top four sides – Napoli, Juventus and Fiorentina – have been more dominant than the rest; the odd one out is Inter, for reasons that will become clearer in the third graphic.

The sheer volume of shots faced by Frosinone is pretty incredible: at almost 21 per match it’s more than double that of the division’s tightest defences.

The quietest attackers have been Bologna, whose average shot tally doesn’t even break into double figures.

Attacking effectiveness

Now let’s look at attacking alone. The horizontal axis stays the same as in the graphic above, but now the vertical shows the average number of shots needed to score each league goal. Therefore bottom right is good (taking lots of shots and needing fewer efforts to convert) and top left is bad:2016-01-18 I1 Att EffThe dominant three sides I mentioned above are all in the bottom right corner again, meaning that not only have they taken plenty of shots but also converted them at an impressive rate. Alongside them is Roma, who have been the division’s most clinical side after Sampdoria.

While I mentioned above that Bologna don’t shoot very often, they have at least been above average at turning their chances into goals. This unfortunately cannot be said of the next most shot-shy team: bottom-placed Verona have needed around twice as many attempts on average to find the net.

Defensive effectiveness

Finally let’s look at the defensive situation – basically take the above chart and replace the word “taken” for “faced” on both axes. Now top left is good – facing fewer shots and able to soak up more per goal conceded – and bottom right is bad:

2016-01-18 I1 Def EffInter may not look particularly impressive going forward but defensively they are in a class of their own. Despite allowing their opponents a relatively normal number of shots, they have soaked up an average of over 19 efforts for each goal conceded; almost double the Serie A average.

While Fiorentina have allowed the fewest shots overall, it has taken around three fewer attempts on average to breach their defence than that of Juventus, who have permitted opponents only marginally more efforts. A more extreme comparison can be made between Napoli and Lazio, with the latter facing fewer shots per goal than anyone else and absorbing over five fewer per goal conceded.
