Daniel Levy and Spurs have said unequivocally that Kane isn't for sale, thus i don't think these bids from Bayern Munich is going to yield anything productive, it is extremely difficult to negotiate with Daniel Levy, especially for a player that Spurs do not want to sell, like Kane.

Having said that, i don't even know if Kane would want to move to Bayern Munich, he is 47 goals short of breaking Alan Shearers record as the all time highest goal scorer in the EPL, if Kane leaves for the Bundesliga he'll not be able to break that record, but if he stays in Spurs or joins another English team, he will break the record after 2 seasons or so. The only way Kane can leave Spurs is if he forces a move out of the club, if he doesn't, then he is content with just breaking goal scoring records and not winning titles.
