I've advocated 4-3-3 (or 4-5-1, depending) away from home for some time now. It worked brilliantly at Crewe last season and then we dropped it after an iffy first half at Stevenage. Never been seen since.
I don't get it - we too often end up with 2 wingers who are passengers and 2 overworked centre midfielders who drop too deep, leaving us with 2 isolated strikers who are also passengers for long spells. Even when we get the ball, we're in no position to attack effectively.
I know we've had 8 very tough away games (all against teams in the top half, Gas excepted of course) but we concede too readily and don't score enough. Time to try something different.
McAllister, Richards & Wroe in midfield, Wright & Ainsworth working with them and a lone striker. I know those two have their critics at the moment but Ainsworth's assists have been invaluable, even when he hasn't played that well, and Wright scores goals, which too many others don't.
I'd stick with 4-4-2 at home though, for now anyway.
