Here is my 4-1-5 which looks like a 2-3-5 when in attack, The inverted wingbacks tucking in and forming a 3 with the DM.
The Inverted wingers are set to stay wide and hold position giving an outlet out wide for the defenders to aim for when possession has been won deep, the DM can also be played as a CM Support with similar results.
In Attack the front three will grab goals aplenty and in the press the entire front 5 will look to press almost as soon as the ball is lost aside from the left IW who is set to press much less often.
Hope you enjoy.
