You are like a broken record. You've had an explanation to what he brings but now you have reworded your question and gone again.
Armstrong scored 20 goals in 40 games last time he played at this level and under Mowbray. His record for Barnsley & Bolton, both struggling teams in the Championship, is irrelevant as he is playing in League 1 now. He has form with Mowbray and form in this league. He's also won major tournaments at international youth level.
If you are expecting us to sign league and cup winners in our current predicament then you are pissing in the wind. Your request of an assured forward that has consistently done it at a higher level shows your delusions. Who do you think will come here with that sort of record?
