Any potential transfer will be settled on the Levy-Kane dynamic and how that plays out. Levy really doesn't want him to go unless the number was astronomical, i'm thinking stupid money here 300m etc. Mainly because he is the only real star man they have besides Son. There is a lot of commercial value and kudos attached to Kane staying, hard to buy the latter of the two.
Kane by all accounts is not one to really kick up a fuss unless he has his limits and enough is enough, where is his mind on this, is he adamant on his decision to go or could he be cajoled by Levy with a wage increase into "sticking it out". I say that because Levy won't give an inch, i think that is a given in all this. Kane will, i think, have to kick up a real fuss, stating stuff to Levy like he won't do a load of press/media commitments and that he will only do the bare minimum, begrudgingly so. All due to Levy's unwillingness in helping Kane get a smooth transfer at a price clubs can stomach.
For us i think what we would pay and what Levy will demand will be a large difference. A cash plus player deal is the only way i see it happening if we are interested. No way are we paying over 100m+ for a 28yo with questionable ability to complete the majority of a season injury free, no matter how good he is. United are watching the pennies as evidenced by re-signing Cavani as their main man with Chelsea a seeming non option going of the growing rivalry between the clubs.
TL;DR What level will Kane go to in order to force a move, how much will Levy try and stop it.
