There's bound to be some crackers, i'll post some shortly... Off the top of my had, Ryan Nelsen is utter quality, and got passed up. Piennar also getting passed up is a bit of a mystery
Pienaar hasn't totally proven himself AFAIC. Undoubtedly he's been in form for quite a while though. Plenty of better central midfielders out there. Biggest one I noticed was Fernando Gago.
