I really don't like where this discussion is headed but here goes another twist at it.
Just to be clear, by this time last year:
Icardi, 8 goals in 11 games, including 2 Champions League goals (with the season starting a week earlier and Icardi out for 3 games). 1 converted PK
Lukaku, 7 goals in 12 games, with 0 goals in Europe (with Lukaku out for only 1 game). 2 converted PKs.
The numbers seem comparable but the context is lacking.
8/18 goals of Inter for Icardi, including games he was missing. For games present, it goes to 8/13.
7/27 goals of Inter for Lukaku. For games present, it simply goes to 7/26. [not even considering that Lukaku directly cost this team 2-3 disallowed goals this season]
Icardi also had 2 assists, so direct involvement to 10/18 of our goals (or 10/13 when present) while Lukaku has no assists thus far.
Minutes played:
2018-19 Icardi-667 minutes (a bit over 7 full games)
2019-20 Lukaku- 960 minutes (almost 11 full games)
This includes a limited squad for the Champions League games last year and a much reduced salary budget for the team that the numbers do not show.
There's no comparison even in the current season where Icardi has thus far 7 goals in 7 games plus an assist. All that's in 466 minutes by the way which are barely 5 full games. And 3 of his goals are in the Champions League.
It's easy to beat someone who's been casted out in the middle of the season. That should not be the target. 20 goals in the league should be the target and at least showing up in Europe.
