Tottenham boss Mauricio Pochettino praised his players for a "job done" after winning 1-0 at Borussia Dortmund.
Spurs will play in the Champions League last eight for the first time since 2011 after winning 1-0 in Dortmund to clinch a 4-0 aggregate victory.
"It was fantastic, job done," Pochettino said. "It was a massive game for us, very tough, but I feel very proud.
"We fully deserved this. We scored four goals, did not concede, and this was against a team that is top of the Bundesliga with great players.
"We suffered a bit in the first half. We conceded more chances than we expected, but that is football. They had nothing to lose and were taking a lot of risks.
"The mentality was good and I'm so happy for the players and the fans. It is so important to be in the quarter-final, but you need to show more if you want to be at the next level."
