Lukaku is now to Mourinho what Fellaini was to Moyes. He has become the poster boy for all that was wrong with Jose. The player that was holding back the young superstars Rashford and Martial.
He has been dreadful this season. While I agree he certainly has got too big, I think most of his issues are psychological. He has always been like this, where he goes through periods of form when he's not scoring that he looks utterly terrible. When confident, he can be a force of nature. Wayne Rooney (the club's all time record goal scorer) was similar. Even in his glory years, when he was out of form, he was really bad and his touch was also terrible.
What disappoints me is that when Rashford and Martial were low on confidence, it was all down to Jose. When Lukaku goes through a similar slump, he needs to be sold. He still has a far better scoring record than either Rashford or Martial and I really hope he can find his form. Top class number 9s are not cheap.
