Regardless of anything, Tottenham Hotspur are still at their own level, they are not better and not worse even though they finished in the bottom position of the Premier League standings, but last season they were able to win the Europa League title, which was enough to make them confident again.
However, there was a big decision taken by Tottenham Hotspur management, namely firing the coach who was able to give them a trophy after years of chasing it, so Tottenham Hotspur management wants change and wants their team to perform better next season with the decisions they made, but I don't think that will be realized.
When I heard that they will be changing their coach, I thought that was not a good decision. In my own opinion, since the coach managed to give them the Europa League after struggling to get that for many seasons now, why shouldn't the management try and strengthen the team? If they have a weak position, they should replace the players and make sure everything is good for the team.
And leave this manager to continue managing the team. I think it will be better instead of chafing the manager. I think changing the manager will even affect the team's performance by next season since the coach will be new and will come with his style of play, which may delay their success during the competition, but if the management thinks that is what they are supposed to do to restore confidence, then we will see by next season.
