I think the Spurs fans are defending their player from what they feel is attack. I can only speak for myself when I say I'm not attacking Kane, but rather pointing out that this talk, in relation to his value is absurd when there's already a status quo proven time and again by the strikers at the elite clubs and what they've done to earn the move to said clubs. By that scale, what Kane has done in the league is pretty good, but outside of it, he is well short on the pre-requisite. Aguero, Costa, Ibrahimovic, Lewandowski, Benzema, Aubameyang, Suarez, Higuain are the strikers at the top of the tree. Look what they did to earn their moves, or in Aubameyang's case. how much he's having to do to get his dream move to Spain.
It's either that, or it's a punt on a much lower priced player who proves himself the hard way from the ground up at the club ala Giroud or what's happening at Liverpool.
Kane being in that bracket with the aforementioned without doing something similar to what they've done to earn their moves, would be unprecedented.
