Mourinho and his side have come under intense scrutiny in recent weeks due to their style of play and their misery was compounded after a shocking exit from the Europa League at the hands of Dinamo Zagreb on Thursday.
Having also been knocked out of the FA Cup and currently sitting eighth on the Premier League table, Spurs only chance of winning a trophy will be in the Carabao Cup, where they have booked a date with Manchester City in the final.
Given the current form of Pep Guardiola’s side, Mourinho says Spurs can only overcome Manchester City if they change their attitude.
“There are some groups [of players] where it is easier to win. That is obvious,” the 58-year-old said ahead of Tottenham’s game against Aston Villa on Sunday.
“[On Thursday], we lost a chance at winning a trophy. I am not saying by winning [against Dinamo Zagreb] we would win the Europa League, far from that.”
“But, we were knocked out of a competition where if you go to the quarter-finals you have a 12.5 per cent chance of winning the competition. So, we can say we lost [a chance at winning] a competition.”
“Of course the only chance we have to win a trophy this season is the [Carabao Cup] final we have to play against a very good team, against the next champions and against a team that match after match show an incredible desire to win.
“It will be a very difficult final and if you want to have a chance to win of course the attitude has to be completely different.”
