We need to play Barkley in "the hole". He is far more suited to playing just behind a centre forward than in the deep role we've seen for most of the season - with our lack of firepower, this has never been the case more. His quick feet and physical ability will cause a nightmare for most teams in this league, so much so that he would likely end up being marked by two players at once which obviously opens up space for other players (think: full-backs).
He has the potential to be as good as Stevie Me was about five years ago when he was playing behind the gender-confused one who's at Chelsea now.
