Tottenham is just in a bad situation right now. It is not impossible for them to come out of this situation. But it will certainly take time. A lot of players are going to leave Tottenham by the time they are trying to fix the problems that they have. Tottenham had a good squad to work with most of the time. But they have failed to actually achieve a good result even when they had a good squad.
With Harry Kane certainly leaving the club it is going to be a lot harder for them to achieve whatever they want to do. A big reason why players are not going to be interested to play for Tottenham they are not participating in the European competition.
Tottenham are always in a bad situation, that's normal for them

As for Kane, it seems that he told his teammates that he wants to move to Real Madrid, but since Tottenham wants absolutely unreasonable money for a not young striker (who has only one year of the contract left), Real doubts the expediency of the purchase. Or did I miss some news?
Agree, for some reason I also always looked at Tottenham never having very good results but the truth is, in the previous four seasons Tottenham made it to the Champions League final and that was a bit forgotten. But regarding Tottenham this season it is clear that Tottenham are having a bad run of results and what's more, it looks like Tottenham don't have the right coach after Conte left. Also, next season I personally will doubt Tottenham completely, because of the impact of losing some of its key players which will certainly have a negative impact on Tottenham's performance next season.
