He's a decent player, but I'm not convinced he has what it takes to succeed in the top. He benefits greatly from having creative players around him who can utilize his depth. He just doesnt have a single wow factor ability. He's decent at everything without glaring weaknesses. Though you can also say that about Thomas Muller and he's world class.
He works hard though and he's a normal down to Earth kid. No weird antics no drama, just trying his best to succeed. Think that's a boon too.
Honestly though
@Sjaakmeoff would be a better source. He supports Ajax. Asking me is like asking Graeme Sounnes if he rates Pogba.
