Christian Eriksen's first-half goal was enough to give Tottenham three points against Southampton at White Hart Lane on Sunday.
The visitors came into the game hunting a fifth straight win but it was not to be. Good work down the left between Emmanuel Adebayor and Nacer Chadli found Eriksen on the edge of the box and his low strike went in off the post to give Tottenham the lead.
Southampton's best chance came in the final few minutes when Ryan Bertrand fizzed a superb cross along the six-yard line and Sadio Mane fluffed his lines from only a few yards out to slice wide of the post as the away side fell to defeat against former boss Mauricio Pochettino.
In the early exchanges, Tottenham came out at a high pace and Jan Vertonghen saw a looping header cleared off the line by Bertrand as the visiting side struggled to keep Spurs at bay.
The Saints' best chance came as Mane pulled a ball back from the byline but Morgan Schneiderlin's effort was blocked by both Vertonghen and Graziano Pelle. Erik Lamela forced a good save from Fraser Forster before Spurs took the lead five minutes before half-time.
Chadli's neat touch gave Eriksen time to strike through the legs of the onrushing Toby Alderweireld and past Forster into the net. There was still a chance for the home side to double their advantage and after being put through b Adebayor, Chadli's effort came back off the post and away when he should have done better.
Unable to break through
In a second half that they controlled more than the first, Southampton struggled to find a way through the stubborn Tottenham defence with Pelle looking an isolated figure for the Saints.
Victor Wanyama was left unmarked on the edge of the Spurs penalty area and following a hashed clearance by Younes Kaboul, but the Kenyan's effort was beaten away by Hugo Lloris.
Southampton's best chance of a point came and went in an incident that summed up their afternoon. A superb low delivery from Bertrand on the left found Mane in the centre of goal from six yards but he didn't connect and the ball rolled wide of the post when any contact would surely have resulted in a goal.
The Tottenham attack did not trouble Forster at all in the second period, but after Eriksen's goal had given them the lead, Pochettino's side saw the game out and Southampton were beaten for the first time since the opening day of the season.
