He had an amazing game yesterday, he's developing really nicely at Brighton.
However, that said, I don't really see him as the kind of CM/DM that we need. He's a bit McTominay-like. He's very good defensively, has very good control of the ball and he can surge and dribble into the opponent's half. But his passing normally is quite timid.
Stats aren't the be-all and end-all of course, but here's a glimpse of how he looks against our current CM pairing for those wondering.
In a more dominating team his possession stats would increase of course, he would have more progressive passes and touches at the attacking penalty etc. He's showing glimpses that he can improve on last year's stats too. But I don't think his passing stats would increase to point of reaching Fred anytime soon. Nevermind the kind of DM I feel that we need in Fabinho or Jorginho (didn't fit).
Personally I maintain that we need a playmaker in midfield first and foremost. One that is also positionally aware and shields the defence through good positioning. Rather than some who is good defensively but limited with his passing.
