Honestly Fred, if you've read any of the Nuno thread or any of the match build up thread to the Leeds game you'll have your answer.
And before Punts explodes somewhere it's more about mindset than any formation we play in general.
Watching some dour defensive performances from 5 man defences isn't fun so I'd rather watch us play attacking football in an Atalanta 3-4-3 style. More like the 2nd half against Soton and less like the first half. Inverted wingers are the key to this (I didn't think Adama could do it but he's having a go at least).
Playing more forwards ≠ goals.
Look at Bayern, Liverpool, Barca, City for examples.
