I think what is interesting is, for all of the talk of our awful season, we are level with Spurs. There is now growing talk of quite a big spend come the summer. I look at Spurs and think they are the biggest one man team going as well. I know Son is good, but he scored 4 in 1 game at Southampton early on, and after that has had a relatively quiet season.
Kane's goals have won them 10 points, if you factor in his goals and assists that is 21 points. If you remove each of those it has Spurs in 12th and 17th respectively. If you work to the premise thatm a replacement coud get half the goals/assists he did and therefore 1/2 the points back (so they lose 5/10 points) they drop down to 11th/12th place. We have seen this season it takes a long way to claw yourselves back from this.
To contradict myself slightly, I do think the big worry for Spurs in all of this is that they price hikm out of a move asking for 100m+. He is left unhappy and inevitably his output drops a bit and the squad are also left unhappy. You get the sense he's played out of his skin this year and through injury to carry them, but not sure how long he will keep doing either for.
