The England striker is set to return from his three-game suspension when United travel to local rivals Manchester City on Sunday.
And former United star Robson feels that the 28-year-old is determined to show that he has matured in recent years.
“The way Wayne goes about the game, works hard for his team-mates and works hard for himself, is an example to everyone,” Robson told ManUtd.com.
“The one thing Wayne has to take on board is that he’s under even more scrutiny now. We saw him get sent off recently and, as a captain, you can’t be doing that. But Wayne knows that – I spoke with him at the training ground after the incident and he’s well aware of it.
“He’s calmed down an awful lot in recent years. When he was 18 he hadn’t matured; now it looks like he’s beyond that.
“But in my mind I think he’s done that because he’s keen to impress, desperate to show people he cares. I don’t think it’ll happen again.”
