Great one mate, because that's what I've clearly done. If you're not intelligent enough to be condescending, you probably shouldn't try.
Welbeck has played for one of the top sides in the country and has failed to impress time after time. He has also played as a front three numerous times but his goalscoring record is little better than Long's, who has played for mid to lower league sides.
I would put money that if Long does sign he would score more goals for us than Welbeck (wherever he plays) next season.
