I don't think you can really include Morgan. I think that Xander would be fancied ahead of Morgan to be honest. McBain also doesn't really offer as much as Xander would do out wide. he is certainly much more of a central player than a wide man. Rankin and Paatelainen fair enough though.
Much the same on the right - Cowie and Hart I see as more central midfielders. Hart has shown to be particularly effective in the middle and Cowie appears to be a fantastic box to box midfielder but I don't think he is so well suited out on the right. Wilson however is a "real" wide player.
Basically I don't see why, when we really don't have that many proper wide men, we are shipping out an exciting talent like Xander who can cause some real damage coming on. He is pacy, tricky and could give defences a real handful.
We have plenty of midfielders that's for sure but not all of them are particularly well adapted to playing out wide.
