hexagon is good only when your opponents do not have strong defensive mind...it is very difficult for hexagon against the team with 5 defenders..
such as: 5-3-2/3n-2w-3mcs-2sts...90% hexagon will loose if follow the advice of the above manager.. hard attacking/full pressing...
Depend on the situation you can adjust your formation..don't just always stick on 1 formation, bro...
