The only speculation to date is by media and people like us. Kane will go if the club get an offer too good to turn down IMO. Otherwise he's a Lillywhite for another season.Sure. But there shouldn’t be any speculation over whether he may or may not resign. That has to be clarified this Summer and then plans can be acted upon in anger.
For all we know, they have a bright, young thing in their radar and they're giving him another year. Maybe they're gambling on him renewing if he actually see's us getting CL again and, God forbid, a trophy?
I understand the nervousness in the fan base, but I've been through this with Hoddle, Waddle, Teddy, Klinnsman, Gazza and many others over the years so, whilst we won't necessarily get a generational talent like Kane in the immediate future, we've always managed to get goal scorers. They may not be as good, but if the system works and others are weighing in with goals, any striker we get would likely be good enough to make up any deficit from losing Kane.
I guess what I'm trying to say is that it's only your own angst that demands clarification. The club may, or should, already know what the situation is and will act accordingly.
For all we know, they fully intend to sell Kane, but are holding their cards close to their chest to get the best price possible. It's all well and good saying "but he'll go for free at the end of the season, but someone will jump the gun, looking to snap him up rather than take their chances. When was the last time an elite player went on a free? Even Eriksen went for near £20M with just 6 months left on his contract.
