Teams constantly adjust their shape depending on the situation, with players changing positions to create new passing options, overload specific areas or strengthen defensive stability. A 4-3-3, for example, can transform into a 3-2-5 in possession or a 4-1-4-1 without the ball, showing how one starting formation can develop into several different structures during a match.
