This discussion with Alex Mason, DOC, Sporting Omaha and Mike Smith, Head Coach, University Heights Academy Boys Soccer, Hopkinsville, KY, breaks down the strengths and weaknesses of the 4-3-3 and the 4-2-3-1.
Both share how they line up defensively and how that changes when in possession. They also explain how their line ups and tactics change depending on if they are down a goal or up a goal late in the game, plus how they can exploit weaknesses in other formations.
