Of course, the scouts and Mitchell are paid to watch him in games and probably pick up on things we can't as fans (off-the-ball movement, perhaps, or footballing intelligence), but from my lamentable Youtube-based standpoint he doesn't seem all that special; decent finisher, decent header, gets into good positions fairly frequently..but doesn't look exceptional in any of those categories, and doesn't particularly look stronger than most, or possessed of any innate physical attributes that recommend themselves immediately to the observer (As far as examples of this phenomenon go, Batshuayi is pretty powerfully built, and Lacazette is just really quick).
