Arsenal legend Wenger gave some excellent insight as to why Spurs earned a marvellous victory against Dortmund.
Arsene Wenger has told BeIN Sports that Tottenham Hotspur earned their 3-0 win over Borussia Dortmund on Wednesday night because of their superior physicality that comes with playing in the Premier League.
Both Spurs and Dortmund were very equal in the first half, with Hugo Lloris denying the likes of Christian Pulisic, Dan-Axel Zagadou and Thomas Delaney - but the second half was a different story.
Indeed, a Jan Vertonghen-inspired performance saw the Belgian -playing out of position at left-back - find Son Heung-min with an expert cross to score. He then scored one of his own, converting Serge Aurier's delivery to make it two.
Substitute Fernando Llorente scored his seventh of the season to make it three against the Bundesliga leaders from a Christian Eriksen corner, and ex-Arsenal boss Wenger believes it was Spurs' strength that won the match.
"Possession was quite similar, as was shots on goal," Wenger said. "In the second half, I felt that the physical power in every challenge made a huge difference. You could see the Bundesliga compared to the Premier League in the second half.
"The physicality and the power made a huge difference. Every time you felt that a Tottenham player could win the challenge, and would the be dangerous."
In what was one of Spurs' best European nights under Mauricio Pochettino, the likes of Son, Vertonghen, Harry Winks, Hugo Lloris and Eriksen all shining under the lights at Wembley.
Spurs' focus immediately returns to the Premier League title race, as they travel north to Lancashire to take on Burnley at Turf Moor in Saturday's lunchtime kick-off. The return leg against Dortmund is on March 5 at the Westfalestadion.
