Tottenham did just enough to defeat Championship side Middlesbrough in their FA Cup third-round replay.
Spurs were gifted a second-minute lead when Boro goalkeeper Tomas Mejias passed the ball to Giovani lo Celso, who cut inside a challenge and scored.
Erik Lamela doubled the hosts' advantage after 15 minutes when he flicked the ball past Mejias after a fine run.
George Saville pulled one back late on for Boro with a low strike from 20 yards out, but it was not enough.
Tottenham, who have won the FA Cup eight times, will play at Southampton in the fourth round later this month.
