Harry Kane scored twice and had a penalty saved as Tottenham fought off a gritty Nottingham Forest side at the City Ground to remain unbeaten.
Forest were positive throughout and began on the front foot but Kane punished them with a clinical finish on the break within five minutes.
Goalkeeper Dean Henderson later denied Kane from the spot and made several more important saves.
Kane confirmed victory for Spurs late on, heading in from close range.
Antonio Conte's side were made to work for their victory as Forest, pushed on by a noisy and optimistic home crowd, kept themselves in the game for large periods.
