A breathtaking second-half display saw Tottenham overwhelm Borussia Dortmund at Wembley Stadium - and take a 3-0 lead to Germany for the second leg of their Champions League last-16 showdown. After a testing first half, the Belgian transformed into one of their biggest attacking threats after the break, providing a sumptuous ball for Son's goal and continuing to send in terrific crosses as the second half progressed - and to top it all off, Vertonghen got on the scoresheet with under 10 minutes to go.
Pochettino was keen to praise 21-year-old defender Juan Foyth, who made only his second Champions League appearance and helped to deny Dortmund an away goal. "When you have a team in front of you like Dortmund you need to respect them", Pochettino said. 'He was fantastic again. We need to feel proud about the performance, so happy but at the same time, calm, because there is still a lot of work to do. 'My players are heroes. He smiles and he creates energy in every single game.
"3-0 is a very good result but at the same time we have to think that we have to finish the job".

Pochettino felt that Son deserved a penalty and found it "unbelievable" that he was booked for diving instead. Sometimes winning games when you're not at your best".
Pochettino devised a clever game-plan that eventually frustrated Dortmund and secured Tottenham's first ever Champions League knockout-round win at home.
"The first half was very hard".
While Borussia Dortmund had the better of the opening 45 minutes, the second period was dominated by the Premier League side, whose pressing resulted in Jan Vertonghen gaining possession, before producing a stunning cross that Son Heung-min duly converted.
"Jan Vertonghen is technically unbelievable and can play in any position".
Working as a pundit for beIN sport, the ex-Gunners boss said: "I wanted to take him from Man City when he didn't get a game".
