Manchester City midfielder Cole Palmer is confident departing teammate James Trafford is on track to becoming "world class".
City goalkeeper is set to sign for Burnley after he and Palmer helped England win the U21 Euros on Saturday.
Palmer said: "Wow. He's so good. You could see it in the academy.
"Even in training, he's so hard to score past. I'm just glad everyone else is seeing it.
"He knows himself how good he is but he's not arrogant. He's a nice lad. He's a normal lad who believes in himself.
"When he first came, everyone was thinking, 'who's this kid?' As time went on, everyone was looking at each other, like 'wow'.
"He just goes about his business on his own. I always say to him - even when we were little - that he is going to be world class."
