Service. If Michael Owen didn't have his through balls, he wouldn't have had as many goals either.
Actually... Owen did not have that many throughballs as many thinks. Most of his goals was inside the box. He was at the right place at the right time. Owen did also create alot his goals himself due to his pace and fast turnings. Comparing Owen vs Eccleston is like comparing a Ferrari and a Lada.
Eccleston is a decent player. But not world class as you mentioned here. If he was world class he would be playing striker for Liverpool regulary.
