Watching Nwaneri, it's like someone found the mold for late 90s attacking midfielders, before the game got divided into positional specialists. and used it to make one last player. I don't think he quite has the pace for the wing either but he doesn't need the pace centrally. His technique on the ball wins him half a second in an area where people fight for 1/10th of a second advantage. He does his man and then he goes back and beats him again just for fun.

He never quite took that final step to earn himself a place among the Zidanes of this world, but jesus christ he could do absolutely anything on a pitch. He was dancing past his opponents. Tell me whose low centre of gravity and effortless close control this reminds you of:
