Pre-imagery: deciding strengths on pentalty (e.g. side, lob, power).
Then
Hear crowd roar. Imagine slow silencing, they become background noise. Visualising the goal frame, the goalie, looking at the posts. Imagine self practising decision-making: instinct or pre-decided penalty type and visualise self visualising the execution in front of the ball.
Visualise ball placement, looking down at the ball. Ball feels cold (unless wearing gloves), solid. Stays still.
Stepping back, counting steps.
Hear referee whistle.
Breathe in and kick/breathe out.
Imagine post penalty exaltation.
