The North London club suffered their 15th Premier League defeat of the season at the hands of Fulham on Sunday (16.03.25) and the 59-year-old manager admitted he can understand fans frustrations, with Spurs languishing in 13th place while continuing to perform well in the Europa League.
Ange said after the game: "Fifteen defeats nowhere near good enough.
"I said to the players, I'm not going to let anyone just think about Europa and nothing else.
"We can't let this league season go the way it has. We've lost way too many games, unacceptable.
"I understand the supporters' frustrations with that."
Ange bemoaned his side conceding another "soft" goal in the 2-0 defeat.
He added: "It was another day where we let a game get away from us when we shouldn't. We had chances to go 1-0 up which would have put pressure on them, then they scored a really soft goal.
"Today the opposition haven't blown us off the park. For 75 minutes we were where we wanted to be, the fact we come out of that game with nothing is disappointing."
Yves Bissouma was subbed off for the second league game in a row and Ange warned the player needs to be "more dominant".
He said: "Sometimes Biss lets the game drift by him. He needs to be more dominant in the way he gets on the ball. The game gets away from him and today we needed more in that position.
"But at the same time Biss and a few others are lacking a bit of confidence."
