Then you probably haven't seen much of him. If you watched him for a couple of games, it would be very obvious that his movement is top, top class, and that his finishing is superb. The combination of extreme speed and strength, his ability to always time his runs to perfection, and always find the right spaces, and superb finishing, makes him an unstoppable goal scoring machine.
There is still room for improvement in his technical repertoire. His technical skills has greatly improved over the last two years, though, and if it keeps improving, he will be up there with Mbappe in a not very distance future.
I agree with his positioning but i find it hard to judge his finishing when he's scoring against the likes of Parndorf and Hartberg. I'm not denying his talent but some here make him out to be a sure thing which he absolutely isn't.
