There are quite a few threads on the forum dedicated to tactics, but i would recommend using a
4-3-3 formation with:
Team Instructions
Emphasis: Attacking;
Passing:Short;
Tackling:Normal;
Pressing:Yes
Player Instructions:
Passing:Team (all)
Tackling:Team (all except DC's and MC's)
Pressing:Team (all except GK and DEF)
Paa To:R/L/C (all)
Free Role:No (all except 2 outer FC's)
Foward RunsYes (all except GK,DC's,1MC)
Run With BallNo (all except L/RMC, L/RFC)
Hold Up BallNo (all except 1MC and 1FC)
Long ShotsNo (all except 3MC's)
Through BallsNo (all except 3MC's)
Cross BallNo (all except DR/L,L/RMC,L/RFC)
MarkingNone (GK,FC's); Man(2DC's); Zonal(rest)
I have had lots of success with this tactic and with slightly different instructions so you might have to experiment a bit.
Hope This Helps.
