Tottenham gave themselves a great chance of advancing to the UEFA Champions League quarter-finals with their performance against Borussia Dortmund on Wednesday, and this goal by Heung-Min Son made a huge difference.
The forward broke the scoreless tie in the 47th minute with an impressive finish off the cross from Jan Vertonghen.
This opened up the floodgates for the Spurs, who won 3-0 at Wembley Stadium in the first leg of the round-of-16 match.
Son has been a key part of Tottenham's success in all competitions this year, but the volley was his first Champions League goal in seven appearances.
