I'm playing a 3-3-1-2-2 (3 CBs, 2 WBs, 1 DM, 2 AMs and 2 STs) and it's working quite well. My lineup is as follows:
Mignolet
Skrtel - Agger - Sakho
Henderson (retrained) - Lucas - Enrique
Gerrard - Coutinho (AML - the formation is asymmetrical)
Sturridge - Su?rez
I'd say the trick to creating a successful tactic with Liverpool is to make full use of the attacking options (Gerrard, Coutinho, Moses, Sturridge and Su?rez) - you want Sturridge as a poacher, Coutinho as a playmaker and Moses as a winger.
I've made my tactic quite possession-based, although it's quite dynamic; so not really Tiki Taka, but I'm sure a counter-attacking tactic would also work well for Liverpool. You probably need to sign a better defensive midfielder, though, Lucas isn't really good enough on FM to be the lynchpin.
Good luck mate!
