|Son Heung-min scored for the fourth match in succession to put|
Tottenham made an impressive second-half show to wholly dominate Bundesliga leaders Borussia Dortmund at Wembley and take hold of this Champions League last 16 tie.
Mauricio Pochettino's team mounted an interesting revival to advance from the group stage - and they made the most of that onerous work to ascertain an ideal platform to reach the quarter-finals.
Spurs were irresistible after a tight first half, Son Heung-min breaking the deadlock 2 minutes after the interval with a side-foot volley from Jan Vertonghen's cross.
Dortmund, regarded by several as favourites with Spurs missing injured talisman Harry Kane as well as Dele Alli, failed to respond and the home team rammed home their superiority in the last 10 minutes.
The outstanding Vertonghen slid in on serge Aurier's delivery and substitute Fernando Llorente headed in Christian Eriksen's near-post corner - with Spurs also keeping a clean sheet to enhance their probability of progressing.
Spurs dig deep to find inspiration how could anyone underestimate the resolve of this Spurs side after the manner in which they have kept pace with Premier League pace-setters Manchester city and Liverpool without any squad strengthening and recent injuries to key figures Kane and Alli?
They survived a fierce first half, when keeper Hugo Lloris saved crucially from Dan-Axel Zagadou's header, to gather themselves for a sustained second-half assault.
And there were heroes to be found all over as Spurs' defence was so assured and the whole side so well-drilled that Dortmund barely threatened after the break.
Son has risen fantastically to the extra responsibility thrust upon him by Kane's absence while Vertonghen was inspired in all areas, not solely in his accustomed defensive position but further forward as he created one goal and scored another.
Spurs might have settled for a one-goal lead had it been accompanied by a clean sheet. to score 3 without reply is dreamland and makes them huge favourites for the second leg in Dortmund on 5 March.
