Honestly I have no idea but I hadn't watched him much up until he came here with the exception of the odd match back in his Bundesliga days. All i know is when he stepped up when Lewy got injured is when he showed hes capable. I think his success is partly do to the service and that cant be ignored but this team just functions way better with a target man up top playing with Müller. Its a marriage of convenience for sure as he really is our only out and out striker but its definitely mutually beneficial. I dont mean to do him a disservice because hes scored some bangers, good interchanges and good finishes not just being in the right place tapping in rebounds or setups that anyone could finish, hes genuinely looked like he fits in.
