I think if we are talking natural out and out strikers than rooney and suarez don't fit in this list. I know alot will disagree but thats my view. Rooney and Suarez are forwards like messi and Ronaldo, they can score alot of goals but offer something different to the team than that. For example if Rooney scored 10 goals this season he could still be uniteds best player, not much would be said about the low goal tally. While if Gomez scored 10 goals and he couldn't be Bayern's best player, because if he doesn't score much goals he isn't a good player. So, for me the best Strikers in the world are Van Persie, Gomez and huntelaar. These lads are goal machines and if they don't score goals they are not much good.
