Gotta disagree. We have more than enough to supply any striker worth his salt and Kane would especially thrive here because he can control a football and facilitate the attack with hold up play. He also isn't a limited tap in merchant. Maybe you're referring to Ruud type poachers.
Kane wouldn't struggle because he can score goals out of nothing - that's something Lukaku cant do
I'm by no means saying Kane is some second rate striker - but I do think that Kane in this current spurs side would score more than Kane in this current United side.
Lucas, Lamela, Son, Aldeweireld, Trippier, Eriksen, Dembele, Rose and so many more are players that create for their central striker.
Shaw, Smalling, Dalot, young, Matic, Herrera, Martial, Rashford, Lingard in comparison do not hold up a strong fight in comparison.
Kane would do fine here again due to his individual abilities & this is why I said Rashford, Martial are thriving here on their individual abilities too - something Lukaku can't do.
Kane would be great but with 10-20% less chances created for him. What he does on his own would continue.
