It looks like he can play in a wide position or central, but he is a technically skilled, dribbler/playmaker. He doesn't play like Cuadrado for example. Like Hazard, who plays in a wide position, he was originally a central player.
From highlights/descriptions, he appears to be an out of this world dribbler with insane ball control. He also appears to have vision, and have a sense of when to pass, unlike some Moroccan players who just try and dribble through an entire team, and end up giving the ball away. His shot appears decent too.
According to whoscored, his weakness is aerial duals, but in mostly everything else he is "very strong" - key passes, set pieces, dribbling, headed attempts (go figure), crossing. He is also "strong" in passing.
He has played in both wide positions, as well as a central position this year.
