From Cardiff all I can think of is perhaps Caulker and Marshall. From Fulham I can't think of anyone who has turned up for them on a regular basis.
Møller Dæhli is probably the first Norwegian footballer in a generation worth taking a punt on.
Very young still, about the size of Pritchard too, but has shown that he can make an impact in the Premier League already. Would probably be a sign him up and loan him out deal for a club our size, but we've done well with that in the past.
I haven't seen any of them, but the youngsters at Fulham like JGL mentions could be decent. I also think Riether at Fulham would be a capable full back backup if we sell Naughton.
