The assumption here is that Lukaku contributed to no goals other than the ones he scored. It is complete nonsense to say we would have finished in the same position without him, maybe without the timing of his goals, but not without him.
If you watch him in the match, he occupies two defenders most of the time, allowing other players to move and score. Not his fault that they miss tap ins etc.
Anyway, as this was in the transfer thread, I replied here, probably should have been in the lukaku thread.
Greatly encouraged by business and prospects so far, more still to do and some people to move on.
