Playing balls into his feet under pressure as if he's suddenly going to be a great target man/hold-up play striker is a big issue. At the best of times it's wasting his other talents, in his current form you might as well just pass it straight to the opposition. If we want to use him as an easy ''out" ball from defence we'd be better off putting the ball into the channels for him to chase than trying to play fast into his feet or lumping it onto his head.
He's at his best when you give him decent service into the box, or on quick breaks when you give him something to run onto or he can use his movement to create space for others. If we continue to get the sort of service into the box as Dalot did against Fulham, Lukaku will prosper as he comes back into form.
