Tottenham have scored a total of 68 goals last season. Harry Kane contributed 37 goals. He has scored 23 goals and 14 assists. Don't you think the team is dependent on him? And he has been playing for Tottenham for a long time. If a player stays in the same club for a long time, it is normal for other players in the club to become somewhat dependent on him.
Kane is a top player in both goals and assists. It is very impressive stats and contributions from him. I guess that is why Kane want to leave Spurs. He feel that he has reached his best but can not bring any title to Spurs and for himself.
Let's not forget that the partnership with Son added a spark to his form. For the first time in his career. Kane was able to make that many assists in a single season something that was not characteristic of him and guess who was at the receiving end of the assists most of the time? Son Heung-min.
If he moved to Manchester City, I don't know if things would be the same again, but time will tell.
Kane, Spurs and England should say thank you to Jose Mourinho. Because he gave Kane a new position and upgraded Kane to a higher level. Without Mourinho, Kane probably still plays as a traditional striker. In the Euro 2020 final match, Kane brought challenge to Italy with the position as same as in Spurs.
In the last season, Kane and Son with Mourinho tactics, have their best in the first half, what happened in the second half is a regret for all. I am not a fan of any of them, Kane, Son or Mou but I see the big changes Mourinho helped Kane and Son.
I don't think Kane will have much space to play in Manchester City and if he joins them, he will play as a striker.
