The thing is he doesn't make a particularly high amount of passes in all his games.
This is against Burnley where he scored and statistically had one of his best games last season
He made the same amount of passes as Rondon. More than his CM partner but Newcastle passed the ball mostly from the back with Schar and the defenders
The match before (Huddersfield) he got on the ball much more :
He almost got on the ball as much as Schar this time. Thats a lot more like what you'd expect from a player people are suggesting might be like Carrick
Against Wolves, again he was up there getting on the ball and making passes.
But then the match before that against Spurs :
Barely on the ball with Hayden having the most passes in CM.
Obviously as a young player you expect inconsistancy, but people are talking like he had 9 or the majority of 9 games where he was an outstanding midfielder for Newcastle in the Carrick kind of mold. But to me it was a handful of games where he got on the ball a lot, and some others where he was on the fringes in terms of on the ball play.
