So wait, now you're making some point that stats are ridiculous and you shouldn't compare players. Weird seeing as you said this earlier:
You can't eat your cake and have it too
Lukaku averaged 176 minutes per goal in all comps while he was here. Last season Martial's record was 155 minutes per goal, Rashford's was 158 minutes per goal and Greenwood's was 144 minutes per goal.
Martial may well prove not to be as good of a goalscorer as Lukaku but in his first season as a number 9 he's proven to be just as prolific as Lukaku was when he was here and we both agree he's a better player. It's weird you seem to be trying so hard to discredit Man Utd players over one who decided to leave us the moment he wasn't undisputed first choice. I personally prefer to get behind the players who stay at United and hope they do well, it's odd that you don't.
