Obviously he didn't have zero service but the service to him was crap for most of the season, he scored 20 whilst feeding off scraps.
His touch and hold up play might not be all that but he's the best goalscorer we've had in a long time.
By that logic, if he scored 50 he could have been feeding on scraps too. As part of the attacking unit, he's involved in making his own service too - if the attacking unit breaks down, he shares the blame.
It is what it is - in Europe, he played against defences where they set up to suit him, and he dominated. Domestically, he failed to perform against defences wise to him and he suffered, because the ball broke down pretty much whenever it went near him.
Yes, we're not setting up to his strengths, and that's a Martinez issue more than a Lukaku one, but ultimately he should recognise he hasn't done enough to improve his play and perform in the league to a standard required.
