Yeah, but van persie scored a nice goal at the world cup, and rooney was buzy marking the cornerflag.
Sadly, thats enough for fifa.
Thing is, overall rating, counts for what ? I dont care about them. I prefer to look at the relevant stats and see how they do. Rooney might be lower overall then Van Persie cause Van has very good shooting/heading/volleys etc wich are highly rated, while rooney is just below, but wins in many mental, physical and passing attributes wich count lower towards overall score
Apart from goalkeepers and defenders, i dont look at it that much
