Why has rooney got poor goal scoring record as a striker every season?

Because their are alot of better players than him who play for Man Utd tbh I hate them all including him I think hes got the lowest because he's the SH!!TEST player in my opinion 4 Man Utd get rid of the bowld ugly c*nt and buy somebody else who is decent Rooney is to big headed and I don't like how he shows off all the time it annoys the F**K out of me!:@@@
