Blog reader W. Rufer sent a scan of a Sankey diagram from his favourite soccer magazine.

Rufer writes: “I found this rather unusual Sankey diagram in a German soccer magazine called 11Freunde (11Friends). It visualizes the career of French international Nicolas Anelka in terms of transfer and lending fees. He started in the youth team of Paris Saint-Germain, changed to their first team in 1995 and got sold to Arsenal for 750’000 € (left side of the Sankey diagram). From there he made his way through Europe, sometimes for incredible transfer fees of about 35 million €. Now, as a rather old player, he earns his money in China.”

The legend also has grey arrows, when Anelka was “on loan” to another club. The change to his current club was without tranfer fee (different blue).

Following up to my last post after the knockout of the 2010 FIFA world cup. Well, things have cooled down a bit now, so here is the completed Sankey diagram showing the tournaments goals.

As one commenter put it, you can “see that Spain’s road to success is a rather boring one (a thin line of 1:0 wins) while Germany was pretty inefficient (big lines, no gain).”

Drawing this was fun, although I was not happy to see my favourite team drop out in the quarter finals already…

In doing the Sankey diagram I found it difficult to handle null flows (that is, explicit zeros, not “no value”) in a Sankey diagram. Also I am not happy with the differentiation of regular goals and penalty goals (brown Sankey arrows). Maybe I’ll come up with a different presentation in time before the 2014 worldcup in Brazil…. ;-)

Inspired by the diagram on the knockout stage of the 2010 FIFA worldcup, I just had the idea to “sankeyfy” it. The width of the Sankey arrow represents the number of goals scored. Penalty goals are shown in different color (brown), but to scale.

Now I have to run for the Brazil-Netherlands match….

Will update this diagram after the quarter-finals…
