What's the gap between amateur players and professional players? Reaction speed, operational level, tactical awareness, overall view, and so on. Not to mention that professional players' teams have resources and forces that amateurs can hardly match, as well as a think tank behind the scenes.
What's the gap between professional players? Their state!
What's the most common phrase commentators say during professional leagues? "Such-and-such player isn't in good form today..." And that state refers to their psychological state. For professional players, the differences in technical and tactical aspects are already minimal; what they're competing on is psychological state.
