i'd play 3n-1-3n-2w-1........defensive, long ball , flanks, hard tackling , own half,zonal , counter on ,offside off...... used this on teams equal to and stronger than me who have used 6 players in central midfield and centrally up front in the past ,and also in a cl final last season........never lost........but its down to you in the end.....i can only tell you whats happened in my experience.....
