I've said before that that I think no matter how much we arrange this team, goals will be an issue, and you can flip the attacking triangle to play 2 strikers and 1 attacking mid. Sterling with Sturridge and Balotelli ahead. Or Sterling and Coutinho with Sturridge ahead. Once Sturridge is back, Sterling will go back to attacking mid, and we could either try Balotelli and Sturridge again or carry on playing two attacking mids.
I'd like to see Balotelli and Sturridge given a run up front together, but that would mean one attacking mid place for Sterling and Coutinho. That might see Sterling moved to wing back but I genuinely hate seeing him in that role, he is so wasted there. I'd rather see Coutinho moved to centre mid, but I don't think thats a good idea either. I want to see Balotelli and Sturridge up front together, but in this formation that would mean dropping one of Coutinho and Sterling or moving Sterling to wing back.
Anyway, goals are a real issue but I don't think its the formation, and I wouldn't want to go back to a 4-1-2-1-2 to test that theory out.
