Tottenham also experienced a difficult thing for them in EPL but I can say Tottenham also has a good percentage in UEL the factor is the teams in UEL right now I say none are impressive apart from Lazio and Man United and Tottenham.
If I tell the truth, I actually have a little doubt that Spurs have a chance to win the UEL title. Maybe Spurs can try to continue their struggle until the semi-finals, but if in the semi-finals Spurs meet one of the favorite teams, they will definitely lose and fail to reach the final round. For Lazio I still believe that their chances are still very good and even for Man United I feel more confident that MU can be really consistent until they reach the final round later. Amorim has planned something good to be able to bring Man United to get good achievements this season even though they failed in the EPL.
Tottenham chances of winning the title are very slim, I'm not sure they can make history anytime soon by winning the UEL because their performance always declines every season almost to the end. This season their performance is also not very impressive, sooner or later they will be eliminated when they meet the favorite team.
Currently Lazio is still one of the favorite teams, but Athletic Club can also provide a surprise. Man United need to improve their performance if they want to go further in the UEL, the inconsistent problem must be resolved immediately.
