Emmanuel Adebayor struck twice in the second-half to ensure Tottenham saw off the threat of Swansea City at White Hart Lane.
Rafael van der Vaart had given Spurs the lead inside the first 20 minutes on a beautifully sunny day in north London, but Gylfi Sigurdsson pulled a goal back for the Swans shortly before the hour mark.
Adebayor, though, proved to be the difference between the two sides, after he first rose highest to head home a corner from Van der Vaart, before nodding past Michel Vorm from an Aaron Lennon cross.
The Togolese striker now has 13 goals in 26 Premier League appearances this season for Spurs, having signed on a season-long loan from Manchester City.
Spurs, meanwhile, remain in fourth place in the Premier League, and have opened a five point over Chelsea and Newcastle in fifth and sixth, respectively.
Swansea have dropped into the bottom half of the table, but remain 11 points clear of the relegation zone.
