Domestic cup

 ( Association Football Terminology ) 

Whereas Points-based competitions such as the Premier League rely on teams maintaining consistent form for the duration of the campaign, the stakes are much higher in domestic cup matches, which follow a knockout format, as everything is on the line during the course of a single match.
