Completely disagree, I honestly think he’s absolutely awful and one of the most technically deficient players I’ve seen in 30 years watching United. As an old fashioned, on the shoulder striker, he is okay; he’s not an awful finisher. No top side is playing with a striker like that.
There was a passage of play in a match last season (I forget which) that summed it up; United won the ball back from a corner and launched a counter, the ball went up to Lukaku, who was in the centre circle with Martial to his left and Lingard to his right, both bombing on to create a 3 v 2 situation. The pass that was on was to Martial as the ball arrived at Rom's feet. A world class striker, like Ibra or RVP, could have played it first time. Most top line strikers would be able to kill it with one touch and then play it. Lukaku, you'll be shocked to hear, took a heavy touch. He then took another to control his own miscontrol, before finally playing the ball out to Martial.
It might seem incidental to the casual observer; he kept the ball and then got it out to the right player, but in truth, those seconds lost to his poor technique meant Martial had to check his run, defenders had chance to recover and the attack petered out to nothing. Elite level football has incredibly fine margins, where every split second counts and far, far too often, when Lukaku is in the team, you see moves that get slowed down by his touch. He can't reliably be involved in build up.
