Esk are you happy with him going missing for the next 3-4 games before he pops up with another goal or two? Because that's what you're getting out of him. As a paying fan which I believe you are, who is willing to travel hundreds of miles to support the team, is that acceptable to you?
Football is a relatively simple game.
Lukaku has two great strengths.
Firstly he is one of the best what I would call 'on the shoulder of the last man' attackers I have seen in 40 odd years of watching the game. That means him facing the opponent's goal and taking delivery of through balls. When he gets that his conversation rate is huge. The problem is that this is most effective when you play two up front, so that one can run off the other creating space in the centre of defence to run into. It's hugely difficult to do playing up front alone as you are usually on a two v one situation, allowing one of the defenders to mark, the other to intercept the pass. That's when some people claim Lukaku goes missing. Me, I look at it and see him isolated and marked out of the game.
Secondly he's one of the deadliest finishers in the box. I don't have the stats to hand but his shots on target ratio is very high and conversion rate high too. The problem? We don't get the ball in the box often enough, or when we do the accuracy of crossing is poor (Deulofeu, Bolasie both v inaccurate crossers, Mirallas and Lennon don't get enough crosses into the box).
Hence my comment about building a team around Lukaku. We need a #10 to play alongside or slightly behind him, plus at least one midfielder who can put through balls through regularly. In addition we need wide midfielders/wingers who are more consistent in quality and frequency of delivery.
