"Scoring goals is not important, we are out of the Champions League. I am still not happy about the result," Son said to 'Sky Sports'.
"I am not a guy who scores goals and is happy but we lose. I am not this guy. I want to win every game, I want to score goals in every game.
"Scoring goals is not important for me now, the result is more important."
It was a tough result to take for Tottenham, who could claim to be the better team over the course of the tie - despite conceding four times and Juve missing a penalty.
"We showed in the past and even in the first leg we have the character and the momentum to fight against the best team in Europe," captain, Hugo Lloris, said. ""But it is not possible in four minutes to concede two goals at this level and a top team like Juve."
Spurs' only hope of a trophy now rests in the FA Cup.
