I really do agree with you here because so far I haven't seen Tottenham in such a position before, infact I haven't seen them the season like this before since I started following football. It's not just that's hit with this bad performance, Manchester United is also in this same boat. Just like you said, if a team like Leicester City and Southampton weren't in the position they found themselves this season just maybe Tottenham would have been one of the teams to be facing relegation this season.
You are totally right it is really surprising to see Tottenham playing so badly this year. For many of us who have watched football for long time they have never been in situation like this before. And you are right Tottenham is not only team struggling Manchester United has not been doing great also.
And Leicester City and Southampton being in even worse trouble is good point. It really shows how bad things have been for Tottenham. If those other two teams were not doing so poorly people would probably be much more worried about Tottenham possibly getting relegated this season. It really shows how unusually bad their performance has been. Let's hope they can start playing better soon.
Maybe this might be a wake up call for the owners, it's not just about building a new beautiful stadium and making revenue from it and then not invest in your team. Yes, Tottenham has some very good players but the management is poor. Just imagine a team like Tottenham, it's because of this kind of mentality that made them to lose a prolific player like Harry Kane, I don't even know what a player like Son is still doing in an unserious team like Spurs.
