Entire list is good, but quoted part could be expanded on low level cups. Imagine you have player with low professionalism and he's asked to play a game in early rounds of League Cup or even that EFL Trophy where youth teams of Premier League teams play. Such player should have very little interest in a game and should play way below his actual level. He should've problems with motivating himself for the match. This way you could get entire teams not motivated enough (due to poor team talk) for a lower league opposition in FA Cup and some giant killing stories would happen.
