Rooney has signed a new five and half year deal worth £300k a week making him the highest paid player in English football history.
It should also keep the England striker tied down to the Premier League champions until he is on the verge of his 33rd birthday.
Rooney has twice rocked United by asking to leave which has ended up with the 28 year old earning himself a new deal.
Moyes is not bothered about the figures that have been bandied around and he hopes his man goes on to become the club’s record goal scorer and club legend, if he isn’t already.
“Wayne has been the best player in England since I put him into the Everton first team in 2003,” Moyes said.
“Since becoming United manager in July last year, I have enjoyed working with him and seeing just how he has developed his incredible talent.
“With his ability, his experience and his desire to succeed, he is a vital part of my plans for the future and I’m absolutely thrilled he has accepted the challenge.
“I said last July that Wayne has an outstanding chance to be a true legend of this club’s long and rich history. He is just 42 goals away from overtaking Sir Bobby our record goalscorer and becoming the first United player to hit 250 goals for the club. These opportunities only come to special players and I’m confident Wayne will set a new record that will take decades to reach. These are really exciting
