Query: Analysis of association football playing styles: an innovative method to
  cluster networks   In this work we develop an innovative hierarchical clustering method to
divide a sample of undirected weighted networks into groups. The methodology
consists of two phases: the first phase is aimed at putting the single networks
in a broader framework by including the characteristics of the population in
the data, while the second phase creates a subdivision of the sample on the
basis of the similarity between the community structures of the processed
networks. Starting from the representation of the team's playing style as a
network, we apply the method to group the Italian Serie A teams' performances
and consequently detect the main 15 tactics shown during the 2015-2016 season.
The information obtained is used to verify the effect of the styles of play on
the number of goals scored, and we prove the key role of one of them by
implementing an extension of the Dixon and Coles model (Dixon and Coles, 1997).
