I think they need a better manager. Tottenham is one of the oldest teams in the Premier League and always loves to fight. It was humiliating for them to have so many defeats this year and to be at the bottom of the league. That's why the management parted ways with the manager, even though they won the Europa League Cup. Now they need a quality and experienced manager like Ancelotti. Of course, Ancelotti will not go to Tottenham because he signed with the Brazilian, but they have to find a coach as experienced and good as him.
Only good manager is not solution of their problem because their performance is at their lowest level, and they needed good improvement which allow them to have good results and consistency which is never been easy because now huge investment with few bold decisions can make good changes.
Tottenham management never been able to invest good funds for having quality players and their suitable replacements but now if they fail again then surely things could be at his worst after sacking of Ange Postecoglou now reports are coming few top players are also ready to leave which could be another dilemma. Just 2 months remaining in start of new season with how they will be manage it's going to be challenging for them because they are having huge problems into their front and their system is badly down due to their bad decisions.
