Don't bite lads. Don't bite!
If I wanted to play devil's advocate you could argue that his Champs League goals (aside from PSG and Barca) have all come against second tier oppo. As for bagging goals against 7th place Lazio - who have shipped a few goals this season - and whilst Serie A teams are famed for being hard to break down with great defensive organisation, it's tough to judge if his performances in the league are not up against world class defenders. Quick look at his Serie A goalscoring record. Not a lot of goals against top 4-5 teams is there? And aside from a brace against a then-11th in the table Napoli, all of his multi-goal games come against dodgy teams.
Was speaking to my mate not long ago after Lukaku bossed England in the Nations League or whatever. How good he looked in that match over 90 mins - totally unplayable - albeit switching between Declan Rice and Harry Maguire - he had a field day. Easy to forget that he is only just approaching his peak years. He will be judged based on what he does in the next 3-4 years I reckon.
But goals are goals, can't argue against the record
