I use dimartino's modified version of the blitzkrieg, the tactic in the share and download part of the forum.
I am managing liverpool and made one tweak.
I tweaked the left F9 to an AF(A).
So my front two looks like this:
Suarez AF (A) - Costa F9 (S)
Suarez has 35 goals in 41 games and Costa 29 goals in 31(2) appearances.
It might be an idea to try this tactic if you're playing a 4-4-2, its sent my Liverpool team on a record unbeaten run, and I should touch just over 100 goals in the premier league. Suarez and Costa compliment each other so well.
I hope this gives you some ideas.
