1 player played almost every single minute he could for 2 season and scored 37 goals in 6,444 total minutes, the other fed on scraps and scored 34 goals in 3,629.
Im not attempting to say I think hes "better" than Lukaku, but as far as replacements go, we could certainly do a lot worse, add in his all round better game and he would be utterly perfect for the way Ronnys blues wish to play the next few years.
