I wouldn't really subscribe to the view that its paramount to have our left and right midfielders getting to the byline and swinging the ball in. In that midfield there is so much reative talent, and goals. All four of them can score, Ireland and s.reid will probably get 10 a piece for their clubs this season (if reid gets fit and gets a run). Keane certainly doesn't benefit from crosses and is much better with the ball into feet or to run onto, balls which that midfield should certainly be able to provide.
one of the reasons i went for this is it allows carsley to fit in, i certainly think he's needed, without sacrificing either keane or doyle.
