TOTTENHAM 2-0 BORUSSIA DORTMUND: Cristian Romero and Dominic Solanke were on target for Spurs, who recorded a much-needed Champions League victory to ease the pressure on Thomas Frank
Say what you like about Spurs but they are now unbeaten in 24 European matches at the Tottenham Hotspur Stadium.
That is some record and however bad the Europa League winners have been at various stages of Thomas Frank's debut season, they deserve credit for their Champions League exploits thus far.
They have lost just once, winning four and drawing twice and this front-foot, energetic display was definitely something to build upon.
Beat Eintracht Frankfurt in Germany, just as they did last season and they could well force their way into the top-eight, bypassing the play-off round.
Victory against 10-man Borussia Dortmund must now be backed up on Saturday when Tottenham travel to Turf Moor to take on Burnley.
Regardless, here are five talking points as Spurs finally got back to winning ways in their penultimate Champions League group phase match.

Solanke the difference-maker
This was Dominic Solanke's first start since last May when Spurs were beaten 4-1 by Brighton on the final day of the Premier League season.
He's been to hell and back with his ankle injury but tonight, all the hard work during his rehabilitation would have felt worth it.
Solanke scored Spurs' second and also appeared to announce that his partner was pregnant in what felt like a rare heartfelt moment at the Tottenham Hotspur Stadium.
There hasn't been much to shout about in N17 this season but Solanke provided a timely reminder that he brings so much to the party.
His physical presence, pressing, threat and all-round hold-up play has been sorely missed this season.
Everyone has been super critical of Frank but maybe, just maybe, he deserves some leeway because he's been without his best striker since August.
Hopefully, Solanke's struggles are now behind him because there is also a place as Harry Kane's understudy in the England squad up for grabs.
Romero leads by example
Despite being captain, Cuti Romero does not always address his Tottenham colleagues during their pre-match huddle.
Here - given the magnitude of this game - perhaps it was not surprising to see him barking orders before kick-off.
In fairness, it seemed to work because Spurs flew out of the traps with real purpose and were ahead through Romero inside 14 minutes.
The Argentine was fired up and he led by example, setting the tone for his team-mates to follow.
It was a cunning finish from the centre-back for his second goal in as many matches.
Porro's red card delight
As referee Glenn Nyberg reached for his pocket and showed compatriot Daniel Svensson a red card, Pedro Porro could not contain his delight.
He paced over towards the sideline and revved up the crowd with his arms, urging them to provide even more noise.
The atmosphere was already rocking but for once, there was a sense that Tottenham smelt blood.
There has not been many occasions this season where that has been the case.
Just a matter of months ago, Porro took to social media to address supporters following the 2-1 home defeat to Fulham.
The players' relationship with the home crowd has been a rollercoaster ride all season but here, there was clear chemistry between Porro and the fans as they cranked up the volume to spur their team on.
This shouldn't be a one off because tonight, it was clear that Tottenham fed off the warmth and energy provided from the stands.
Bergvall injury frustration
It wasn't quite clear what exactly Lucas Bergvall injured but what is for certain is that he should have come off the field a lot sooner than he did.
The problem seemed to start when he clashed knees with Emre Can, though initially he did not appear to be in any pain.
But after continuing, he then hit the deck and required treatment on his lower leg.
Bergvall tried to soldier on but he was in a world of pain and grimaced after every action.
Eventually Jun'ai Byfield was summoned for his Tottenham debut and that definitely lifted the crowd.
What's concerning, however, is that Bergvall has endured an injury-hit campaign and cannot seem to stay fit.
We'll have to wait to hear how he recovers but Spurs could do without another fitness problem as they finally bid to turn the corner.
Reliable Danso
You'll struggle to find a more reliable 'third-choice' centre-back than Kevin Danso.
He is the ultimate professional, he rarely moans about his lack of minutes and always does a top job whenever he fills in for either Cristian Romero or Micky van de Ven.
That was no different tonight when he flourished at the heart of defence, turning in a warrior-like display full of grit.
The Austrian made five recoveries and five clearances and also helped Jun'ai Byfield settle once entering the field.
Players of Danso's character are worth their weight in gold, particularly in the midst of a crisis - he deserves immense credit.
