Dan Davies:Sitting in my office in New York watching it. The word "soccer" is banned in our office!

Khurshid Patel: Watching and working at the same time all the way from Edmonton. #bbcfootball, external p.s. United will pull off surprise win in a reverse fixture :)

Antony Jee: Could you hear my scream from NZ?

Rattling along at proper tempo now as Dortmund look for an early response...

The second half started like the first with Tottenham pressing high like they did time and time again in the first 10 or 15 minutes of the game.

It came down that left-hand side and was brilliantly whipped in from from Jan Vertonghen, and when he had a chance to knock it in Son just peels off the defender.

The centre back Dan-Axel Zagadou has just lost his man and the goalkeeper has no chance.

Sophie Gayter: Brilliant goal from Spurs. What a cross from Verthongen and a cracking calm as you like finish from Son who has to be one of the most in form players in Europe at present.

James: Zagadou-do-do lose your man concede a goal...

Ming: Heung Min Son is world class. He would get into any XI in the world. Not one team would turn him away. Not one. What a player.

That goal is Son Heung-min's fourth European goal at Wembley. Only Harry Kane (six) has scored more often at Wembley in European competition.

Jan Vertonghen doesn't really like playing at left-back, never mind wing-back, but he delivered a superb cross there. Wonderful assist from the Belgian. Wembley rocking.

Away we go!

Christian Chanel: Not as far as the NZ guys, but I live in Houston, Texas now and am watching the "soccer" (hate that) in my office.

Chris Hall: Watching from the beautiful island of Rarotonga in the Cook Islands, not quite as far away as NZ as the crow flies though. Do I at least win the most remote/random location award??

Here come the players again...

Guido van Asselt: Solari clearly has not seen the game against Feyenoord then. Get stuck in and Ajax fall apart. Don't give them the room to play

By the very letter of the law, Dusan Tadic was a smidge offside so I guess VAR got that right. But there is no way on earth that any linesman would have given that in real time. It's hard to explain without seeing it but Tadic was running out as the ball was heading back the other way.

About 0.00005 seconds later he was back onside....

Rio Ferdinand on BT Sport: "I am just happy to be here. Jadon Sancho is so exciting. A kid who is 18 years old is scaring the life out of the opposition.

"I love it! He knows he is going past the player it's just a matter of how. It is just unbelievable to see."

Ajax have absolutely dominated this game.

Thibaut Courtois made a brilliant save to deny Hakim Ziyech.

Then the controversial moment came from a header from a corner that then went in the back of the net but it was Dusan Tadic - belatedly - that was ruled offside. They had deserved to take the lead.

Ajax would be disappointed to be one-nil up at half time.

Ajax know that 0-0 is a bad result for them and if they don't win here then they only have themselves to blame as they have had enough chances.

Can you get more central than this? The dot at the top of this touchmap is where Dan-Axel Zagadou was positioned when Hugo Lloris was able to pull off a terrific save.

Jadon Sancho is not the only youngster out there making a big impression at a club away from his home country.

Juan Foyth made just seven appearances for Estudiantes before quitting Argentina for Tottenham for £8m in August 2017.

Tonight is the 21-year-old's 18th appearance for Spurs and he is doing quite well.

Tottenham have found it really hard to break Dortmund down.

The midfield of Dortmund have done really well.

Tottenham have struggled to get Christian Eriksen and Son into the game.

Dortmund are soaking the pressure up and when they win the ball back they are explosive.

Don Uorri: Interesting tactic playing with wing backs and wanting to put crosses in yet not playing with a proper striker.

Odel: Spurs fan here. I have to say I am a bit disappointed with our final balls tonight. Dortmund have been slightly more dangerous going forward.
