If Martinez is after Moses, then I can see us playing a front 3, should we get him.
Howard
Coleman Jagielka Distin Baines
Gibson
Fellaini........Pienaar
Moses........Kone........Mirallas
Gibson would have to be extremely disciplined there though. And, essentially, 'do a Carsley' for us.
Pienaar would be able to help Baines out somewhat, but their partnership would be over, and Pienaar might have to gain some discipline himself for a more central/defensive role. Alternatively, would Osman be a better choice there?
Finally, a lot of this hinges on us capturing Moses, or someone similar. Assuming we don't, I'd prefer to see a 4-2-3-1, with a greater emphasis being placed on us passing it across the deck.
