I still think the future is a 4-2-3-1 formation for us but if the experts say that OBZ playing in a 4-4-2 is likely to unsettle Villa, they may have a point for this particular game. However, the repetitive, predictable and unsuccessful monotony of the hoof ball we played against Everton, prompted by OBZ's selection, must NOT be repeated.
I certainly wouldn't play 3 at the back. We have no recent experience of playing that formation and this is no time for radical experiments like that. Despite our results, we have had some promising spells in recent games, playing a more settled team rather than Harry's "names out of a hat" selection process.
