Lukaku has undoubtedly been good overall so far, however I think he has been overlooked in the big games. Without him against Spurs we wouldn't of won, to setup Martial's goal and get us a vital 3 points. He can't be judged against Liverpool really despite his one chance in that game, he had very little or next to no service. Lukaku has exceeded my expectations. He just has to keep it going and keep improving. He himself rightly said that he isn't the finished article and it's good when a player themselves acknowledges that. It shows they have the right mentality.
Particularly enjoy the way he starts deep, lays off the ball and then moves forward. Or drifts our wide to isolate a player. Even when he's not scoring, he's helping the side. He's never going to be a great passer, but he has excellent movement and good link up play.
