Without wanting to beat a dead horse, because at this point there mightn't be anything original left to add in this deluge of negativity about him, but the glaring contrast between Lukaku and his opposite number was there to be seen tonight. Neither of them had their shooting boots on today, but Kane was tracking back and winning the ball or at least pressuring our player in possession, he was bringing his teammates into play with his ability to hold up the ball, he was creating space and options with his runs and just looked threatening every time he got the ball facing goal. Compare that to Lukaku whose sole contribution in the first half was to stand offside and then chastise his teammates for every pass that wasn't inch perfect, infact the sum total of his performance was one shot on target, the ball for which he seemed to wait an eternity to bounce conveniently enough for him to hit (giving the keeper more than enough time to set himself), it's just clear he's not technically good enough and arguably the worst #9 I've seen at the club in my lifetime.
Compare him with the rest of the attack, ballers like Lingard, Rashford, Pogba, Martial, Sanchez, Mata and he just sticks out like a sore thumb. For all his athletic ability his lack of balance renders his strength redundant, he's not at all dominant in the air and his overall presence on the pitch is almost paradoxically lacking. I got behind this transfer at the beginning of the season but it's clear now he's not only not contributing enough himself but he's holding back the rest of the talent in terms of playing time and playing style.
