First of all, the reasons are different:
1, La Liga King's Cup:
The tournament was held in 1902 because Carlos pedros, former president of Real Madrid, proposed to hold a football match to celebrate the accession of Spanish King Alfonso XIII.
2. La Liga Super Cup:
1947, Copa Eva Duarte was held in the name of his wife, Mrs. Peron, to celebrate Juan Domingo Peron's becoming the Argentine president. 1953, the game was suspended because it was ignored. It was not until 1982 that the game resumed and was officially named the Spanish Super Cup.
Second, the competition system is different:
1, La Liga King's Cup:
It was judged by the media as a cup to help small clubs, and was eliminated by mixing four Spanish clubs "regardless of grade". B-level, C-level and D-level clubs that have passed the qualifying round have the opportunity to compete with A-level clubs.
2. La Liga Super Cup:
The original two teams were changed into four teams, and the champions and runners-up of La Liga and the King's Cup both qualified for the competition. If the league and the King's Cup overlap, the number of participating teams will be postponed to the third and fourth teams in the league. The competition consists of two semi-finals and one final, and there will be no three or four finals.
