“The designations given to formations rarely tell the whole story. For example, when does 4-4-2 become 4-4-1-1 become 4-2-3-1? And what if the right-sided forward tucks in to allow the right-back to overlap, but on the left the forward stays wide and the full-back sits back, sometimes shuffling into the middle to form a de facto back three. How would that be denoted?” World Soccer – Jonathan Wilson
