Surely if we'd had any indication from Kane's camp that he actually did prefer a move to United and was willing to kick up a fuss to get that move, we woulnd't have walked away from it earlier in the window and signed another striker instead?
Kicking up a fuss is different than just selecting an option between clubs. Kane would never push to leave, either it is not his character or does not have a good agent. But if he had the offer on the table, he would most probably select us I believe.
Also, IMO, the only difference between now and early summer is in what position you find yourself in. Early summer, he would be the must signing for us. Now, he is just a great bonus signing.
We have a striker so that we can negotiate from a stronger position. We have a price set from Bayern, so that we are not getting dragged into a long saga. If we were to do this, now is the time. ETH wanted two strikers. We can place our offer, can also raise 10% the one of Bayern as a sweet bonus and see how Kane reacts. If he wants to come to us he can reject Bayern and give Levy a headache since he will have to choose United or losing him for free next year. Nothing to lose here from a United perspective.
