And the new Republic of Ireland assistant coach has no problem with people comparing with himself.
Keane said: "He probably plays a little like me, maybe not as aggressive and is possibly looking to mature in terms of his personality on the teams over the next few years but that will all come.
"That comes with maturity and when you get games under your belt. But from the way he trained today, and the game we had, he was getting in very good attacking positions and making very good forwards runs which I think is always something I did when I was a young player, particularly at Forest.
"But I don't want that to be twisted round that I am comparing him to me, far from it.
"He is certainly, in terms of getting forward and hopefully over the next few years getting a few more goals to his game, he is going to be a top midfielder. I do think you need to have a few goals in your locker unless you are that real sitting midfielder.
"He is a very good player. Clearly he is a good player or Roberto Martinez would not have taken him to Everton, if he didn't think so.
"I have looked at him over the last few years because Wigan is only down the road from where I live so I have been to see them a few times. He is certainly progressing very very well and certainly when he steps up a level, I have seen him against the very good teams and he has stepped up, which is a very very good sign. My first impression over the last two days is that the boy has a chance of being a top player."
