The striker opened his account for the season against Crystal Palace last Saturday after a Man of the Match performance and he carried on where he left off against Bayer Leverkusen on Tuesday night with two goals which took him to the 200 mark for the Reds.
Many people have praised Moyes' man management of Rooney since taking over at Old Trafford in July, but the United boss insists it's Rooney himself who deserves all the plaudits.
"Don't for one minute think I am going to take the credit. The credit is for Wayne Rooney for getting himself the way he is. We are here to help make him better. It is up to Wayne to do it. He takes the credit for that," Moyes told radio reporters on Friday. "He was always a great player, even when he was leaving Everton he had the potential. He had all the ability in the world. Could he pull it all together? He has proved that over many years.
"Everybody is aware of what Wayne has done since he left Everton. I have only had a chance to work with him for three months here, but he has knuckled down really well. He has done his training. Everything he has done he has done himself. He has done it to make himself better.
"The big thing is he got himself into really good shape physically. He looks lean. He is back to being his aggressive self again. He is fast and hungry. I needed all those things from him if I was ever going to get Wayne back to the level he is at."
