Due to the 1977 competition being seen as a minor failure the
Polish Football Association decided not to support the competition, not making this edition of the tournament official in the eyes of the football association. For this edition the 16 I liga teams were again invited, however only 11 agreed to take part in the tournament, leading to the introduction of
Diósgyőri VTK,
Tatabánya,
Szeged LC, and
Kaposvári Rákóczi from the Hungarian leagues, as well as
Górnik Zabrze from II liga. Due to the tournament not being officially included into the football league's structure, it is difficult to find information other than the final.
Final Górnik Zabrze won the 1978 League Cup. ==Winners and finalists==
