Morrison was booted out of Manchester United in January 2012 by Sir Alex Ferguson after a series of indiscretions and Noble conceded his attitude is in contrast to that of a year ago, when words of advice from captain Kevin Nolan fell on deaf ears.
He said: "Me and Kev had a chat with him on the way home from a pre-season game and said: 'Rav you've got so much ability, if you can channel it and learn to tame yourself then you'll be a fantastic player for us'.
"Then he didn't come in for the next three days!
"But he's done brilliantly this pre-season. He's not been late, he's turned up to every session, he's trained hard and obviously he's getting the benefits now."
