I’ve mentioned the same thing since he joined, but I put it down to a lack of ability. Firstly, there is his poor movement which makes it difficult for him to find space to receive the ball in shooting situations with consistency. But more importantly is his lack of footballing ability, which means that other top forwards, he cannot engineer enough shooting opportunities when he does have the ball. You have to earn a shot on goal at this level. Lukaku cannot either work angles for himself to get shots away, not take a good enough first touch to get a quick shooting opportunity. If you watch players like Liverpool’s front 3, Kane or Aguero - they get so many more shots off from pretty much anywhere within 20 yards, whenever they get the ball. They are constantly, twisting then unleashing, spinning then unleashing, hitting them with heir first touch, or creating a yard with their first touch and shooting with their second. All that part needs to be done in advance for Lukaku so ideally he’d have only the goalkeeper between him and the goal whenever he receives it.
