Morgan is convinced Bartley has a big career ahead of him.
He said: "It's difficult to start comparing people but you look at 'Jag' and they have similar attributes. Kyle is 6'4 and to make a good centre half you need to be a good size. He's a great athlete too. He's good in the air and as you expect being an Arsenal player he's comfortable on the ball. If he works hard and he keeps progressing then he has everything to make a top centre half."
Morgan also believes the youngster has become a real asset to the Sheffield United dressing room.
"Kyle's done really well. He came at the back end of last season, settled in well and made some good performances. We've been lucky enough to get him back for the start of this season too. Kyle's put some good performances in. He's a great asset to have. He's come and wants to play first team football and wants to learn his trade."
