In an amateur context, pressing is all but impossible. It is hugely demanding physically, requiring almost constant motion and thus supreme levels of fitness. By the time of Michels and Lobanovskyi, the shortages of the war years were over, nutrition was good, and sports science (both legal and illicit) had advanced sufficiently that players could keep running for ninety minutes. This was a stage of football’s development that stemmed as much from enhanced physical possibility as from advances of theory.
