I don't know that we should be throwing £100M at Kane for a number of reasons:
First, he's 30, and like every other aging striker we bought (whether they rely on pace or not), they fall off a cliff quite quickly because quickness in some form is imperative for a striker.
Second, Spurs is built around Kane, the fact he scores for fun there doesn't mean he will in our system (let's be honest, he probably will though - I mean, he did it for Conte, José, Poch, whoever, and for England too).
Thirdly and most importantly, EtH wants an aggressive pressing team, Kane could seriously negate that as I don't believe he's able to keep that up, similar to how we became painfully slow in the press with Ronaldo.
