Yes, 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.
This Tottenham change if coach have spark alot of controversy that make me to question whether if the club performance over the years has been about the coach or the players. Is it because they finished almost been relegated that made the club to sack him or there is more. They won the europa league anyways, I believe their aim was to focus on Europa more since they didn't make it to the top of the table and no way of being relegated.
If you look at Manchester United, they did exactly what Tottenham did, they mostly focus on where they had an edge and that was the europa and unfortunately, Tottenham was the team that won the trophy but it's Tottrnm manager that got hit on the head. Funny thing is that they are going to be qualified next season in the Premier League and Champions league, but they sack him still. I hope the new person or the assistant coach take the league else the mockery is going to be on another level.
