Robin van Persie claims his partnership with Wayne Rooney is blossoming because of the way the pair interchange positions between striker and midfielder. Van Persie has scored 10 goals for United since his summer move from Arsenal - helped significant by his forming an immediate understanding with Rooney.
Van Persie told the club's official website: "I call it a nine and a half because you have two positions, the nine and the 10, and we are both nine and a half.
"We are just helping each other out. We both play behind and a bit higher up. It seems to be working well and I am very happy with Wayne - hopefully we can keep it going."
