Ange Postecoglou enjoyed his first Premier League win as Tottenham manager thanks to two second-half goals against Manchester United.
Pape Matar Sarr put the hosts ahead with his first Spurs goal, cooly guiding home a side-footed half-volley from six yards after Dejan Kulusevski's cross ricocheted off Lisandro Martinez.
Red Devils defender Martinez then scuffed Ben Davies' mis-hit shot past his own keeper Andre Onana to gift Spurs a second late on to put the result beyond doubt.
The hosts almost led earlier, hitting the woodwork twice in a matter of seconds late in the first half as Pedro Porro's shot crashed off the bar before Luke Shaw deflected Sarr's return ball on to the post.
