I was talking about Lukaku as he was towards the end of his time at Everton. At per his level then the bolded bits are 100% not the case. What you're describing is him as he has been here, when he's being used in the wrong way.
Lukaku in that last Everton season was a better striker than Hernandez is/was, as reflected in his rate of return in the PL that year (25 goals in 37 games) being significantly better than Hernandez' best ever rate of return in the PL for us (13 goals in 27 games), despite Hernandez having played in a much better side.
Hell, even Lukaku's league returns for us last year (0.47 goals per appearance) holds up against Hernandez' best ever year for us in the league (0.48 goals per appearance).
Lukaku scored 43 league goals in his final two seasons at Everton alone (74 appearances), as opposed to the 49 league goals Hernandez scored across the all eight seasons he has featured in the PL (143 appearances). Given Lukaku was still just 23 at that point, it's pretty clear he had a hell of a lot more potential than Chicharito.
The idea that Chicharito would outscore him here simply doesn't hold up. Nor is it feasible that Lukaku could score that many goals for a relatively poor side whilst being (as you seem to think) unable to move, unable to control the ball, being easy to mark and being unable to anticipate anything.
