Made some stunning saves from Alli and Llorente,and was unfortunate to see the latter end up squirming to Moura's feet and consequently flying past him into the net. His use of the ball wasn't always perfect, mind. 

Chosen over Veltman to match Spurs' pace in attack, and dealt reasonably well with the challenge of Son. 

An exemplary header to give Ajax the lead, eerily similar to his goal in Turin. As Spurs' turned the screw in the second-half he wasn't allowed to look as assured as he usually does, but he nonetheless found a way through it all, throwing himself in front of everything that moved...until the 96th minute. 

 Struggled on the occasions Lucas Moura ran directly at him, his passing was frequently poor, and in the end he couldn't hold the rearguard together.

Had his reactions been slightly sharper, he may well have turned in Lloris’ claw away of De Ligt’s shot. Struggled defensively in the second half against Moura.

Regal in the first-half, but even he began looking addled and hassled when Spurs went direct in the second half.

His touch, passing and movement was at times divine in the first-half, but he faded from the game in the second-half.

Substituted just before the hour mark, his last act to get in Onana’s way to allow the ball break for Lucas Moura to rifle home Spurs’ second goal.

Intelligent movement prefaced a stunning finish for the second goal. Should have had a second of his own in the second half, when flashing the ball narrowly wide. Then came even closer, when rattling Lloris’ left-hand post. Ajax's most persistent threat.

You may, like this reporter, remember Dolberg plodding about uselessly in Denmark’s Nations League game in Dublin last Autumn. He repeated the performance tonight, managing to be entirely peripheral to Ajax’s ceaseless flow of first-half attacks. A late replacement before kick-off for the injured Neres.

Neres' injury in the warm-up shunted him from his central threat, and while he retained a threat, his final product was occasionally lacking. 

Dealt with everything he had thrown at him, largely jitter-free. 

A weak-link for Spurs again, and was much too weak in a challenge that ended in Ajax’s second goal. Were his World Cup heroics really less than a year ago? It feels now as if it happened in a parallel universe.

An exhibition of front-foot defending as Spurs went on the attack in the second-half. 

Perhaps nobody more delirious with Moura's winner than Vertonghen, having missed a sitter minutes earlier. 

After an underwhelming first-half, he was arguably the game’s most dominant player as Tottenham went berserk in the first 15 minutes of the second-half. Made the most of the space ahead of him; most notably in nutmegging de Ligt in the build-up to Spurs’ gorgeous first goal.

In the battle of the former Southampton players, it’s fair to say that Tadic got the better of Wanyama. Heck, Matt Le Tissier would have outperformed Wanyama tonight. Sitting at the base of Spurs’s midfield diamond, he was totally overwhelmed by the speed and precision of Ajax’s passing and movement. His horror movie lasted 45 minutes before making way for Llorente.

Nobody encapsulated Spurs’ half-time transformation better than Sissoko: having struggled in the first 45’, he was sensational after the break; hurtling through challenges, drawing defenders and using the ball intelligently.

Flitted around the edges of the first-half but grew ever more influential as the game wore on into the second-half. 

A stunning touch for the winning goal: Alli stood up when Spurs needed him most. 

Devilish and dangerous, but not quite as precise as he has been thus far this season. 

A hat-trick! In a single half! In a Champions League semi-final! 

His introduction changed the game, with Daley Blind and the rest of the Ajax defence unable to handle his physicality. Although he didn't score, its impossible to separate himform the chaos from which the goal were scored.
