Tottenham slumped to another Premier League defeat after Rodrigo Muniz and Ryan Sessegnon scored late on to pile the pressure back on Ange Postecoglou.
Muniz made the breakthrough for the hosts on 78 minutes after receiving the ball from Andreas Pereira and tucking a neat finish beyond Guglielmo Vicario.
Sessegnon then returned to haunt his former club just before time, collecting a punt downfield and holding off Ben Davies before bending home with his right boot.
The result leaves Spurs 10 points adrift of the top half of the table.
