I think you should go for a striker proven at Championship level. Someone with vast experience, reliability and can definitely fire you into the Premier League single-handedly. Someone who is physical, good in the air, finishes well and just basically has brilliant all-round play. That's why I believe Nick Proschwitz, a German striker currently playing for Hull City (A.F.C or Tigers, depending on your preference), would fit the bill perfectly.
I'd rather my 12 year old dog than Danny Graham and yeah he has, which is the frustrating thing because he's clearly got goal-scoring talent, but obviously prefers less fans (well less pressure I suppose).
