Here is my 4-2-3-1 with 6 attacking positions, 2 supports and 2 imposing central defenders. Your number 9 and number 10 will have to be strong enough as they are the essence of this tactic. Your striker will have to be formidable in finishing and physically imposing while your number 10 will have to be very good in seeing the game and passing. Your 2 midfielders will be "underused", they pass a lot but can make a lot of mistakes if they have too much attacking profile. Your 2 central defenders will have to be quick to compensate for the rise of the 2 attacking fullbacks. They will have to be good in the centre and on their right foot (a right handed player on the right and a left handed player on the left).
