Morgan is happy Maguire stayed with Claude Puel's side, and says he keeps getting better and better for club and country.
Morgan said: "Ever since he's come in, he's been a revelation. I think he's settled in so well, for me he's just got better and better. The more his confidence has grown, he's stepped into the England set-up and it looks like he's been a part of that set-up for years.
"The confidence he has on the ball, the way he starts attacks, he's got a lot of attributes for a big central defender. He's had a lot of attention on him over the summer, over possibly going to other teams but I'm glad he's stayed here."
