Tottenham had to fight for every inch of the pitch as they earned a 3-2 win at home to Brentford.
The night began with a mobile phone power light show, which twinkled well enough with a bit of the Prodigy's Out of Space. The star here looked nailed on to be James Maddison - hungry, searching, probing from the start.
But for Tottenham's early pressure, Brentford began to exploit the space around the defence.
A narrow offside decision spared Spurs' blushes in the 13th minute, Roeslev denied by the rules. But then a minute later Neal Maupay had a goal that counted, beating Romero to the ball after Vicario spilled Toney's strike.
While Spurs had moments going forward, frustration grew, with Brentford showing guile in slowing the game down and playing on the crowd's annoyance.
On 38 minutes Richarlison had the ball in the net with a deft chip, but he was judged to have fouled the defender. Replays suggested there was minimal contact.
Ange Postecoglou had seen enough by half time to decide a change was needed - Pierre-Emile Hojbjerg and Brennan Johnson brought on for Rodrigo Bentancur and Dejan Kulusevski.
Something worked. First Werner and Udogie worked their way into the box for the latter to score. A minute later, Werner put a ball across which found Brennan Johnson at the far corner to stroke in.
Within 10 minutes, Richarlison had also found the net after Maddison engineered a chance that was blocked.
It looked like the game was done and dusted at 3-1, before Destiny Udogie had a funny turn and apparently failed to see that in front of his keeper was Ivan Toney, to whom he passed the ball. The striker looked surprised, but finished well nonetheless.
The Spurs attacks remained free flowing, but while there was no panic at the back, the crowd were certainly aware of the narrow margin.
Maddison will be credited with one assist but he will have hoped for more. The midfielder lasted nearly 88 minutes before coming off for Radu Dragusin, brought on to see out the game.
Into injury time, Werner was retired to warm applause, with highly rated youngster Jamie Donley brought on.
1. Timo Werner (6)
Awareness of Werner's pace down the line seems to have grown since the City game in the FA Cup. Now it needs more end product. As the game began, it seemed to be the Timo everyone thinks they know. But assists in the second half demonstrated what he's there for. Photo: GLYN KIRK/AFP via Getty Images
2. James Maddison
Back in the starting XI, the attacking midfielder looked bright from the start, finding Werner wide (offside) and then Kulusevski (onside and industrious). But he grew frustrated at being unable to find a breakthrough - and at Brentford's gamesmanship. It was an impressive game back in his legs though, a reminder of the creativity have had to to manage without for so long. Photo: Glyn KIRK / AFP via Getty
3. Destiny Udogie (5)
A moment of madness/complacency saw Udogie pass back to Toney to give Brentford their second goal. You'd think it'll be put down as a "learning experience". Photo: Ryan Pierse/Getty Images

Brentford exploited the gaps at the back left by Tottenham's style of play, but the centre backs played well nevertheless. If you're going to be chasing strikers, you want Micky van de Ven to be the one doing it. Photo: Ryan Pierse/Getty Images
