In praising Rooney's admission about below-par performances, Steve McClaren also added that he (Rooney) was not the finished product.
"When players of this standard receive criticism, they have to prove themselves on the pitch.
"That is exactly what Wayne has done. Now he has to do is consistently.
"He admitted himself he had a point to prove and he has gone a long way to doing that.
"We all know Wayne is a threat and I repeat, he has the potential to be world class. I am delighted with his goal but his overall contribution to the team was very good. He got better and better as the game went on."
