You have Lucas playing behind Sahin on the right and Allen on the left of the middle 3. You can either play Gerrard on the right of the attack with Suarez in the middle and Borini on the left, or have Gerrard in the center right behind Borini and Suarez who can tuck in around him a bit. All 3 of Lucas, Allen and Sahin can really pass the ball. Lucas is a fantastic tackler, and Allen was one of the top tackling mids in the premier league last season, with more tackles than any Liverpool midfielder if I'm not mistaken At that point we don't even need Sahin to be a tackler, but more of an advanced roll (Lucas as defensive play maker, Allen as the box-box type player, and Sahin a bit more attacking.

Personally I see it as the first to keep a better 4-3-3, and it will allow us to use the wings a bit more as well as keeping Suarez central. He does like to roam out wide, especially down the right tho, so I wouldn't be surprised either way.
