In 11 aside football, it is hard for any individual at any level to drag his team to victory week in week out unless there is an element of unity and cohesion across the entre team. The pitch is simply too big and spaces too vast for one man to cover single-handedly. Furthermore the ball travels faster than the man, so the use of a colleague in a better position is generally always the better option than going it alone. Simply put, you will not succeed in structured football unless you can perform in a team environment.
