Spurs have a back four tonight.

Spurs had three centre-backs marking Dusan Tadic who played as a false number nine in the first leg. It meant Ajax had an overload in the middle.

When they switched to four at the back and Moussa Sissoko came on, Spurs got some joy and were probably the better side. Ajax won't change in how they play but Spurs are versatile. They could play with a diamond but I wouldn't be surprised to see them match their opponents.

All set?

Tottenham manager Mauricio Pochettino on BT Sport: "It is a fantastic night. It's an occasion to enjoy, to play football and to deliver the job. It's important to have players available, we still have some missing but Son is back.

"Jan Vertonghen, I don't know if he is going to play in a mask or not, my advice is not to but it his decision, with the doctor.

"It's an open game, we are 1-0 down, we need to win th egame but we can do it in the first minute or the last."

Yes Stephen. The Uefa Cup and the Cup Winners' Cup are not the European Cup, are they.

We had some lovely times in the museums on Ruel Fox's stag do, and it absolutely was well behaved. Amsterdam is a fantastic city with vibrant coffee houses.

This stadium has plenty of energy in it and it is reflective of the city.

STAG DO CHAT CLAXON

Last night Chris Sutton mentioned that he went to Amsterdam for Ruel Fox's stag do. Hopefully hear a bit more about that as the night goes on...

There does appear to be a nervous energy in the stadium and the pressure is on Ajax in front of their fans.

The stadium is filling up beautifully but with what happened last night, nobody has a clue what could happen.

Half an hour to go. My thumbs up/down polling was a big hit last night so let's try an early one tonight.

Will Tottenham qualify for the final? Thumbs up for yes, thumbs down for no.

Another 50 more and people will stop calling you Danny, Daley.

Ajax are winless in their last three Champions League home games (D2 L1). They could become the fourth team to reach the Champions League final with more away wins than home wins that same season, after Manchester Utd (2010-11), Juventus (2016-17) and Real Madrid (2017-18).

Ajax will attempt to reach their first Champions European Cup final since 1996 (losing finalists against Juventus) whilst Tottenham would become the 40th different team in Champions League/European Cup history to make the showpiece game, and the first to reach their first such final since Chelsea in 2008.

Almighty roar inside the Cruyff Arena as Ajax come out to warm up. I've never been to a game there but it's very much on the list.

Brilliantly, they play Rihanna's 'What's My Name' to welcome Andre Onana to the field...

The game is finely poised. Nobody underestimates Ajax anymore but the pressure has switched because people expect them to deliver tonight.

Spurs are dangerous but I think they got it wrong tactically in the first leg so can Mauricio Pochettino come up with a game plan to counter and beat them.

I think it's the Tottenham team we all expected. A lot of this comes down to Son-heung Min tonight. He has been their most consistent player this season and he was missing in the first leg. If they can give him the service, I really think they can do this tonight.

This is a young Ajax team who are confident but the pressure is on them at home. They beat Real Madrid and Juventus against all odds. It's in their grasp now, but that is why the heat is on them.

In the first 20 minutes or so last week Ajax were absolutely brilliant. Same again tonight?

Tottenham boss Mauricio Pochettino makes two changes to the side that went down at Bournemouth on Saturday.

Will Jan Vertonghen be wearing a protective mask? The Belgium defender is in for Davinson Sanchez after suffering a head injury in the first leg, while Victor Wanyama gets the nod ahead of Eric Dier.

Son Heung-min starts having been suspended last week.
