After years in which his off-pitch activities made the headlines, the Manchester United academy graduate finally appears to have found his way with West Ham.
The 20-year-old scored an early contender for goal of the season in Sunday's 3-0 win at Tottenham and has this week linked up with England Under-21s for the first time.
It has been three years since Morrison was last involved with an England side and manager Southgate has seen none of the disciplinary issues that had previously hampered his career.
"I've not recently spoken to people that have been involved with him in the past, but I've spent time speaking to other people who are involved with him now," the Young Lions boss said.
"There are lots of good people at West Ham that have got him in a good place.
"I think it's for us to create an environment here where he can express himself and feel comfortable, and that he can trust the people around him. He's a charming lad. Anyone who meets him would tell you that.
"How do young people learn? Unfortunately usually by making mistakes. It's what you do thereon that's important. It's lovely to see him playing the way he is."
Last season's loan with Birmingham appears to have turned Morrison from boy to man, with manager Lee Clark describing him as "the best young player this country has produced since Paul Gascoigne".
Not that such words meant a great deal to Morrison as he did not know who Gascoigne was.
Southgate joked he probably did not know who he was either - "they (the players) think I'm a bloke who sits with Roy Keane on the telly" - but knows his talent is no laughing matter.
Asked if Sunday's goal against Tottenham was Gascoigne-esque, Southgate said: "We've got at least three players, maybe more, who have the ability to do things that are out of the ordinary.
"When you're playing at international level, the best players in the world can beat people.
"That's the difference. I was with a Premier League manager who I greatly respect and he made the point that, if you look at the great players in history, they could all beat a man as well as pass and finish.
"That ability to go past somebody, as Ravel did and Raheem Sterling and Wilf Zaha can do.
"They're creative players and we can't develop those skills. I suspect they learnt how to do that in street football, in a park, in cage football, whatever environment."
