Man Utd boss Ferguson confident Van Persie will start scoring again
"Robin doesn't need a rest that's for sure," said Ferguson.
"He is a strong lad with a great physique.
"It's disappointing that he wasn't awarded the goal at Sunderland, I can understand that because it took a wicked deflection, because the shot was fantastic.
"All strikers have little dry spells - you always hope it ends quickly. It is just part of being a striker."
