Bailey clearly has shitloads of pace so not sure what you're on about. Pretty much every goal he has scored for us has been him outpacing defenders before scoring.
His delivery was poor, but we've got to be smarter in the way we get the best out of him or alternatively, if they're going to swamp him with a 2 or 3 man press (which they did consistently) then plan to exploit that vacant space. Ramsey and McGinn aren't the midfielders to do that and Ash isn't the dynamic full back Cash is to help.
