Hmm I doubt Harry Kane will leave EPL to join a lower league like Bundesliga. I can understand La Liga move but I don't think he will be interested in other offers.
Real Madrid was a recent target that seems to pull itself from him. I don't recall other news
In the last few weeks it looked like a possible transfer of Harry Kane to Bayern Munich was already impossible because there were so many news that claimed that Harry Kane wants to stay in the premier league in order to be able to beat Alan shearers goal record there. Yesterday though a german newspaper reported that this is not true and that Bayern is still in contact with Kane. If this is true then a transfer would not be impossible. It all depends on him and where he wants to play.
