He excels in his technical abilities: His dribbling, passing and crossing are pretty much accurate, either he uses his left or right foot. his holding up the ball is good, but he has a different profile: he's a very proactive midfielder that constantly search for exploits on the opposition back line. I suspect that his stamina levels, which are clearly above the average, contributes for his will to keep going forward.
His decision making might frustrate you sometimes, because in the last third he's the type of player who prefers to go for the final pass / go for the shot rather than recycle possession. Sometimes this will be a very good thing because most of the opponents are not very used to this kind of players nowadays, but it can backfire his pass accuracy / completed statistics / shot accuracy.
His pace is good, but not his strongest asset, and same can be said about his strength, but he has a quite good balance which makes him a player quite difficult to knock off.
His defensive contribution is quite valuable and a lot of counters start with him. He is a very professional player when defending, doing his pressing very well and try to cut the space and passing lines rather than press and tackle. He's not the player who can outmuscle most of his opponents, so I think he's doing it right.
His defensive positioning sometimes is a let down, but his determination makes it up for it, because he will run his socks off to recover. He's quite a determined bastard tbh.
But... he's one of those players that needs to feel needed by the fans. It affects his morale. But I would say the great majority of the players are like this.
