Tell me then what qualities he brings and how he is such the team player you make him out to be. I personally found him selfish and more interested in himself, but I am open minded to your observations
Undoubtedly, he can be selfish when in goalscoring positions - as many prolific goal scorers are. They have great self belief and always back themselves to score. That's what makes them so good at what they do.
But being selfish in front of goal and being a team player are not mutually exclusive. There's far more to being a team player than merely providing assists for team mates (something which Kane does plenty, by the way). For England, in this World Cup, Kane was asked to change his normal game; to come much deeper and allow the likes of Sterling and Rashford to run beyond him. That's why he had so few opportunities to score. He did a thankless, unglamorous task reasonably well, often without support - winning headers from long balls; holding the ball up; drawing fouls; drawing markers to free up space for others etc.
For Spurs, Kane is even more of a team player. He works his nuts off - pressing, making great runs, passing. All in addition to scoring a hatful. So, while there are undoubtedly parts of his game that could do with plenty of improvement, to describe him not merely as "not a team player" but, in fact, as "not a team player at all" is woefully wide of the mark.
Why was my last comment stupid - do explain
I'm guessing because you made a scapegoat of one player on account of one incident a third of the way into the game when the truth is that there were plenty of reasons why England lost with plenty of people responsible.
