Everyone, and I mean absolutely everyone, relies on some sort of service for goals.
If you're trying to say that a guy like Vanpersie can't score without being fed the ball two yards from goal, than you are insane.
If you're saying he needs a different type of service to someone like Walcott, than fine, but don't get carried away.
Blokes like Henry may score 4-5 individual goals a season that make us all sit up and take notice but he also rarely went in for the brave chances in the six yard box and he didn't score often with his head. It's just a different approach with the same result.
VanPersie was our go to guy for two solid seasons, let's not pretend he needed chances handed to him on a plate. Neither does Dzeko.
