Trying to be realistic I'd look at:
Marc-Antoine Fortune - Old now but done decent at West Brom since he gone back there from loan at Donny, could add depth/experience up front especially if we sell Miller
Nick Shorey - Experienced LB, position not a priority though and might stay in PL.
Sam Ricketts - Just been relegated, experienced, Welsh and can play either side of defence, would be a great squad addition IMO.
David Jones - Was really good for Derby and Wolves and once again another Welsh player to add to our squad, would be a great addition to the midfield.
Michael Kightly - Self explanatory although probably go to another Prem club.
Simeon Jackson - Great striker who is proven in the Champ and has scored a few goals when played for Norwich this season, we need strikers and he'd be a fantastic addition.
Björn Helge Riise - Was good at Sheff Utd on loan and can play CM/RM, would be a decent squad addition.
Ákos Buzsáky - Experienced midfielder who has shown glimpses of quality for QPR this season, can play anywhere in midfield or behind striker and good at set-pieces.
If I had to pick three it would be Ricketts, David Jones and Simeon Jackson
