I've said it for a few weeks now but I'm so pleased with how he's trying to improve his all round game instead of just playing like a poacher; the drive and desire he was showing last night for that 2nd goal was brilliant. For the first goal he used pace that we've not really seen from him so far this season and bullied that defender, his decision making with back to goal is very good, always looking for the man in space instead of playing it safe.
He's not a target man, we need to keep playing to his strengths and giving him the ball a few yards in front of him, punting it 50 yards and expecting him to take it down is not something he's capable of. Only time we should really be playing into the air for him is for crossing, although we still don't have any particularly good crossers.
He'll benefit a lot from having players like Sanchez who often looks for the through ball, and Pogba when he's on song too. Our biggest problem with Lukaku is that we aren't getting him involved enough for my liking.
