Bibliography
Sources, reading tips and further literature
We consulted the Kicker Sportmagazin in its editions from 1946 to issue 52 of 2019 as the primary source. In addition, the archives of Transfermarkt.de were used, which we consider to be the most comprehensive publicly accessible football database in Germany.
Further sources include the DFB and DFL archives, Imago Images photo database, and the extensive online archives of the Süddeutsche Zeitung, FAZ, Spiegel and Die Zeit.
