Knowledge gives confidence. Learn from your experiences and watch referees perform. At the end of the day your ambition must be to gain promotion into the middle of this league. Develop some ideas of how teams play. It's not a case of prejudging more a case of learning and gaining in confidence in your own ability.
Contact Always remain in contact with the referee.
Look, to see where your referee is. Watch him at all times, looking for his positional situations and his movement. Maintain eye to eye contact, even if the referee is not looking at you. When that little ricochet comes you'll be looking and will have seen the little directional signal that assists you. Remember it is all about helping and assisting.
