- Real Sociedad have won their sixth title ever: two LaLiga (1981 and 1982), the Supercopa a Espana in 1982 and three Copas: 1909 called as Club Ciclista San Sebastian vs Espanyol (not recognized by RFEF), in 1987 versus Barcelona and in 2021 vs Athletic Club.
- La Real have become the first Spanish team to have won a Copa final in a 1-0 with the goal coming from a penalty. Indeed, it was their only shot on target of the game.
- Athletic have equalled Real Madrid (from 1918 to 1933) as the team to lose more consecutive Copa del Rey finals in competition history (five, from 1985 to 2021).
- Mikel Oyarzabal has scored 89.5 per cent of his penalties taken for Real Sociedad in all comps (17 out of 19, after missing the previous two before this). Only Sergio Ramos (18) among LaLiga players has scored more penalty goals than him since the beginning of the 2018-19 season in all comps (17, same as Lionel Messi).
