Yeah, their desire for the trophies are going to be tougher with competition is increased and things are looking not easy many clubs are having big investments which are going to help them for having better results but here Tottenham is surely also needs change into their strategy and finances as well if they want to win trophy specially after end of Antonio Conte it's looking more hard for them to have any positive result in near future and if they lost Harry Kane which is looking possible than it's end of hopes.
if you look at the rumors that are spreading it seems that Tottenham will lose next season because several teams have offered a bigger salary for Kane and for me Tottenham don't need to think too much about holding Harry Kane but at least Tottenham have to think about increasing their finances to get some new players who can dominate stronger team.
If selling Harry Kane earns more to buy a few players for me that would be better than having to keep one player and not knowing if I can get a trophy in the summer.
