Tottenham is one of the teams in the top 16 this season, they are one of the teams considered to be able to compete for the championship title. but I don't know how far they will be able to survive, because they have repeatedly failed in a competition. Especially if you compare their performance in the Premier League for example, their performance in the Premier League this season is very disappointing. Usually they are in the top 5 competition, but this season they have been eliminated far from that position and are still struggling to improve it.
Most likely Tottenham realize that they have no chance to compete for the Premier League title anymore, and they are also aware of the team's condition which is getting worse day by day, in 14th position, they really didn't expect to be there, the focus taken by Tottenham in several important matches in the Europa League makes them have to focus there because the Europa League is their chance to win a more prestigious title than the domestic league.
I don't know what happened to Tottenham that they declined in form drastically. They started the season pretty good but all of a sudden, they drop form, was inconsistent and accept defeats easily. Tottenham is one of the clubs that the bookies chose to be the favorite club to win UEL, but with their current form, it's impossible. All hope is not lost though, if only the coach can work on the team for a better performance, winning the trophy is possible.
