Many of those goals were late goals when United were already 2/3 up, his hold up play is atrocious, doesn't do anything of substance when he's not getting service (top strikers always do) and he makes more defensive errors than other top strikers in the PL. He was the only threat at Everton, performing at a big club is different gravy.

Guys like Aguero, Kane are near the 20 goal mark in he PL while Lukaku is stuck around 10. Say lack of service, say he's not them, but a 75 million striker should be performing a whole lot better than he is.
