It's often said that good players will always want the ball. Why? Because they BELIEVE they will achieve results. They feel this way due to constant repetitive training so skills and techniques become a HABIT.
BELIEFS and HABITS are neural connections in the brain created by repetition of thoughts and actions over a period of time. Once wired, then and only then is a genuine, deep down in the gut feeling created that leads to peak performance.
To excel in football you need to possess these feelings and the only way to achieve this flow state is through constant technical repetition - something that can only be done through private training.
