Lukaku was already a unit as a teenager though. And once he got his body between the defender and the ball, there was no stopping him.That worked well for Lukaku. Lack of muscle and bulk aren't his problems...sorting his feet out and not falling over them needs work first.
His last 2 goals were masterpieces of finese and timing, muscle and bulk nowhere in the picture
Barry looks like a brisk breeze would do him.
He’s come on a lot already this season, but he does need to improve physically, which is something the club seem to be working on with him.
