Second-half goals from Harry Kane and Heung-Min Son saw us come back from a goal down to win 2-1 at Borussia Dortmund and cement top spot in Group H of the UEFA Champions League with a game to spare.
It was another display of maturity and clinical finishing on the big stage in Europe and we fully deserved the victory, which was our 100th under Mauricio Pochettino.
Both sides produced some tidy football in the first half and it was a moment of quality that opened us up. Andriy Yarmolenko's flick set up Pierre-Emerick Aubameyang to drill in as we went behind for the first time in the competition this season.
But back we came and after Roman Burki saved well from Christian Eriksen and Eric Dier in the lead-up to half-time, it was Kane who was on point to crack home an equaliser out of nothing in the opening exchanges of the second half.
Son, prolific against Dortmund during his career in the Bundesliga, then bagged the winner with 14 minutes remaining after great work by Dele Alli to retain possession on the left, making it an unhappy birthday for Dortmund manager Peter Bosz.
Substitute Fernando Llorente went through on goal late on in an entertaining and atmospheric Tuesday night encounter but a heavy touch denied him his first Spurs goal and there was a moment of concern for everyone in the stadium in the aftermath as keeper Burki hit his head on the ground and was carried off on a stretcher.
We remained in control throughout the period of stoppage time that followed to keep up our European momentum and consolidate first place with 13 points from a possible 15.
