Aye, and you also said you 'wouldn't be surprised' if Lukaku got 40 goals. It goes without saying that would have put him in the conversation for most productive goal scoring seasons in the club's history.
Those expectations, and I'm not digging you out for it (they were shared by many posters here), were ludicrously over the top based on what he'd shown in his career to date. The backlash against is now going too far the other way.
Whst encourages me is the aspects of his game that aren't good enough are improving in front of our eyes (albeit in fits and starts) and he's still racked up solid numbers.
