Fair comment, makes complete sense.
I wouldn't be criticising Lukaku at all if it looked like he was still putting a shift in, but he was knackered overall and out of form. My problem with him is that he's looked like he's downed tools completely since the international break.
He could do effectively nothing for the rest of the season and still be our stand out performer this season; but it will be a massive shame if he doesn't finish the job he started this season, as he could have made himself an indispensable purchase for a few big clubs in the summer if he did.
I have the feeling he's downed tools because he's laying the groundwork to force a transfer, and that's by Everton being as bad as possible in the run in to justify his need to move on. And if that's the case, he's bang out of order.
But it's difficult to tell. An out of form Lukaku might just look incredibly lazy, instead of being incredibly lazy.
