Harry Kane fired Tottenham Hotspur into the Champions League quarterfinals as his winning goal at Borussia Dortmund in Tuesday's return leg sealed a 1-0 victory to wrap up a 4-0 aggregate success.
On Monday, Spurs coach Mauricio Pochettino had demanded they "finish the job" after beating the Bundesliga leaders 3-0 in the first leg at Wembley.
His Spurs side delivered, soaking up everything Dortmund threw at them in a one-sided first half before Kane's goal just after the break killed off the hosts' spirited challenge.
"It's always difficult in these type of games, you don't know whether to defend or attack," said Kane, who singled out Spurs goalkeeper Hugo Lloris for praise after a string of key saves.
"They had a few moments. In that first half we needed everyone, defenders blocking it, Hugo saving it, that's what Champions League is about -- you need everybody."
This is the first time Tottenham are in the last eight of the Champions League since 2010/11 when they bowed out 5-0 on aggregate to Real Madrid.
"We have showed that we have the quality, we can build on the first-half performance, but we need to score goals," said Dortmund captain Marco Reus.
