I don't consider him world-class, but I think he is excellent, just below world-class. His price should be around 70 million pounds, but in today's striker's market it is what it is. He WILL improve us, not as much as Lewa or possibly Haaland, but he will.
I don't think anyone would have something against this happening if the price was lower. But it ain't our money, guys, and we got Kante for 30 millions, Mendy for 20 millions, Azpi for 10 millions, Mount and James for free. Sometimes you overpay, sometimes you underpay. We will overpay for him, but for about 25 millions, not for 50 like we did with Kepa.
Also, I get the feeling that WHOLE WORLD is put on strikers' backs, reading this comments. Would he bring us Premier league, would he bring us UCL, would he improve us? I don't remember anyone asking those questions about let's say Kounde, 70 million pounds rated defender that has only one good season under his belt. Or about Kepa, 80 million keeper, when he was getting here. If you ask me - Mount and Havertz will bring us Premier league, and UCL, again. Not Lukaku, they are better players than him. But Lukaku will help THEM massively, and that is what we should think about and forget about his price tag.
