so, the question is, who is the player who has skills equivalent to Kane? and whether the player wants to join Spurs while the team  still struggling to win the title in EPL.

currently it is difficult to get high quality striker players while I am not sure whether Spurs can afford to spend a lot money on pure striker player and you can see that most of the pure strikers who are very reliable have very high market price unless Spurs can produce new talents in players young people like Kane were previously trained at Spurs until they have the skills they have today.
therefore, what Spurs currently need is not just striker player but enough to get midfielder player who has good talent to help score more and this is a more sensible way than having to buy pure striker player which will be very expensive and I am sure that the team they are coaching Postecoglou can achieve great achievements if he gets the right midfielder and the reason I say this is because this team had a good performance after losing Kane.
