I think he owes us another season and he knows it. Hopefully he doesn't start playing well so much so that Chelsea would want to keep him. Then in the summer he should reject every other destination and join us for one more year.
He doesn't owe anything at his current state. And I don't wanna get my hopes up on him for next season because we should be looking for another alternatives.
Regarding his performance last night, he was actually doing good things in the second half, which is still nothing impressive but considering his lack of playing time and his current form, that's at least a baby step towards his eventual returning in form.
First half was brutally bad, but let's not get harsh over it. His confidence seems to be at bottom as well, so.
All I want from Lukaku is just to perform at least good enough in these remaining matches. That way, we will have more options in our attack and Dzeko will have his proper rest in some matches so we can rotate between Dzeko, Lukaku and Lautaro. And I'm not even mentioning Correa because he's a zero.
