Maybe but we lack real width and if the midfield three were Barton , Jennings and Baker/Thomas the we dont miss out too much .Problem is its then 3 of the midfielders only and our midfield is probably our strongest area, players wise.
Depends how high we could get the wing backs up the pitch, if we could get them into the byline often it would be goodI wouldn't mind trying that formation, but although I'm not sure it would give us that much more width as our two full backs are our width in the diamond. What it would do is give some protection at the back, however of you played with 3 CB's and Jennings sitting I don't think it will add anything.
That was my thinking ,get them to really press high up the pitchDepends how high we could get the wing backs up the pitch, if we could get them into the byline often it would be good
