Vertonghen, who scored his first ever Champions League goal to double Spurs lead with a fine finish, admitted it was a "special" night for him.
Favourites: "Real Madrid are always the favourites in the Champions League". 'The manager told us at half-time what we needed to do tactically, ' said Harry Winks.
Heung-Min Son continued his fine scoring form for Spurs with the opening goal on Wednesday - his ninth goal in 11 games against Dortmund - and the South Korea global is also refusing to believe the job is done.
Tottenham went agonisingly close to opening the scoring in the seventh minute when Lucas Moura's volley fizzed wide of goal, the Brazilian having controlled Davinson Sanchez's header on his thigh.
"If they had spoken to me, we would have met each other and I think Tottenham would have agreed to speak". The visitors enjoyed their fair share of highlights but were not clinical in the final third - that was when they took part and had the ball at their feet.
The France worldwide had to be at his acrobatic best in the closing minutes of the half as Dan-Axel Zagadou rose to meet Jadon Sancho's cross, the goalkeeper clawing the ball away at full stretch.
Son converted Spurs' first shot on target at Wembley on Wednesday as the Bundesliga leaders were made to rue a string of first-half misses. We have to be on it from minute one to full time.
"Today we won 3-0".
"We've got to go out there and understand that we can't give up goals like that, because there's still a second leg - that it's not going to be easy to play here and we've got to lock in and be able to defend crosses".
