The stats don't tell the whole story in this case. If you have an eye for talent you could tell very early that he's going to be great.
Also, he's played the equivalent of 12 games if you count his minutes, had 2 goals disallowed and at one point the team didn't generate a single chance for him for more than 160 minutes in the league.
EDIT: He's tall, strong, pacey, getting into really good positions be arrive at the end of chances and he has surprisingly good technique for a striker. He also seems to be up for the occasion every time we play a big game and didn't look intimidated at all vs Arsenal or Bayern's defenders when we played them. He has all the tools to be a world class poacher and it seems like his mentality is great too.
