It seems that Tottenham are indeed very patience with their manager Ange Postecoglou as he was not getting replaced even after his horrible performance for leading Tottenham close to the bottom of the table after 30 games played. I guess if Tottenham are not having the luxury of being able to acquire so many big superstars players into the team at the transfer market, it won't be a surprise to see them dropping into the relegation zone with Ange Postecoglou in charge as the manager.
I am pretty sure next season Tottenham management will replace Ange soon because that is what the team needs if they want to rise but I have not heard the latest rumors about who will replace the coach soon there are only a few rumors that have been circulating for quite a long time. And regarding the purchase of several star players if for the attack line I think there are already quite a lot of star players in their squad including Son and it can be seen even though they are in 14th position in the GF standings they are very good. So from here it is clear that their defense line is very bad and Ange lacks the ability to make his sensitive area solid so that the dismissal must be done immediately.
