Very good observation. I was with my mates watching the game and said the same about Lukaku. For all the learning of the game through watching videos and all, his footballing IQ could be improved. He needs to mix up a little bit and stop buying into the "i am more of a scorer, wanna be more all rounder etc".. The crosses from Mertens wss always with him passively waiting at the far post, and as such Varane or Umtiti would get to the ball first. On occasions when they slipped out, it would be too close to react effectively. Also, i felt he was too static and made it so easy for Varane. Make some offball runs down the wing, and be an option when Witsel, Kdb or Hazard have the ball. Keep moving, and focus and anticipate better. He seems to be looking to make those runs when he has the ball at his feet, but offball running tends to open up spaces. Lastly, i thought Hazard was always playing for himself and wasn't utilising Lukaku well. That said, he has a good tournament but his touch, finishing and sense of positioning meant there is really only specific ways to bring the best out of him, and its definitely not through the middle against a well organised defence.
